Here some ideas and advice. Do it yourself!
Plan ahead.
Updated 5/16/2020

How to do it-

One- Try it:

Try it as a test live stream to facebook.
Do it the day before you plan to go live
Make it to your page and make it so only you can see it.
 

When you start the video, start performing your program about 2 seconds later.  ( I allow 2 seconds for the stream to be stable.  ) Then the Show has started, and you are On! Take it away!

By trying a
test stream to your page, not public, for you only,
you know if the picture looks good, and if the sound is right.
You don't have to look at the camera and ask is this working?

Watch yourself and learn, and fix as required.

When you try it for real, make it public on your page.


Note about phones-
They are sensitive to room reverb. Outdoors can work well. You have no mix control, either for voices or instruments. Your big problem seems to be echo. Don't get too far away, or the room noise and echo competes with your music. It can sound hollow, and you sound farther away.  You want to be up front on your stage. If you get enough sound for the phone, they can work well. If you don't volume can be very low. Good phones seem to produce good sound.

Two:About video-

Camera position is important. Eye level will look good. Landscape mode will look better than portrait.. Phones will work, but a simple cheap video camera  like a Canon Vixia works way better. Your ceiling is not that interesting, and we don't need to see it.

Think about background.
Think about lighting.
Both help keep the focus on you and the music.

Three-Sound:

A pretty dead room does not distract from the music, and keeps the focus on the music.
If you use the phone / camera mike you lose a lot of sound  control. Outdoor can work well. Indoors in a damped room can work well.
Your enemy is a live room with too many echoes.

Camera position is important. It will determine the balance between voice and guitar. Indoors room echo and noise become important. Would you perform a concert, with the mike two feet away? It works only in a no reverb environment.

If you have a mixer and a mike, it is a good choice. A DI for the guitar helps. If you mike it separately, point the mike down a little towards the 12th fret. The vocal mike, pointed up a little towards your voice. (A little hf boost goes a long way. Don't overdo it.)  Try the
Test on facebook. Does it sound good to you?

The mike placement is very important.

Do not back off 20 times what you would use in a live performance. You will get lost in the room sound.
The mike should be 2 to 4 inches from your mouth. Thank you for making the point, Mike Birch, that more than one performer, more than one mike Same rules apply for each mike.

Use your mixer. A cable from your mixer to the camera / pc is your new friend. Lack of it is a bad idea.
If your mixer has a usb output to your pc, that is good. If not, the audio output can go directly to the phone, or to the pc.  Most have an audio input. Last resort is to mike the speaker, about 5 inches. Have the PA turned as low as still works for you. All that helps control room noise.

If you try to use the phone mike, you have a whole new set of problems. It is often marginal. The mike needs to be close or you get hollow room sound, and it usually needs to be further from the guitar than from the voice. Position is what balances your voice and guitar. Do the
test and see what you get.

Just setting your phone down, or using your web camera, does not meant you will get flattering videos, or that the sound will be good. Careful about live rooms. And no, not every room will work right without planning for the sound. The miking is very often the difference between a really good video, and a very marginal one.

(My software lets me enter a delay
for the sound to bring it into sync.)

Outdoors, with the camera placed carefully, may eliminate many problems. 
Dan and Shannon showed this in their videos.

Erin Ash Sullivan and Emma, with guitar and banjo no less, did harmony, inside, and the sound and overall mix was pro grade!  The answer is unusual and interesting. They prerecorded it with a video camera, and the the sound come from the sound guy with an overhead directional boom mike!

They are invited to do a full show when the covid is no longer a problem.

Samples

Our system

It uses a video switcher and 1080 hi def cameras. The switcher feeds the live stream to facebook or youtube.

Rode M2 supercardioid vocal mikes, M5 cardioid instrument mikes, and instrument Direct Inputs feed into our digital mixer. The mixer output goes through an AD and into the pc that is running the video switcher.

We have 5 cameras and as many title slide and videos as we can mentally handle. The audio mixer can handle 20 input channels. We can both stream live and record 1080p60 video effortlessly.

Software:

I tried OBS, and did not like it.

I tried xsplit and did not like it.

Studio 6 looks very interesting
but not for 32bit win 7 machine,
it only installs on c:,
It's expensive.


If you have ever seen an access station control room,
check out vmix.

I tried vMix, became a fan, and use it.
One of the most clever pieces of software I have seen.
