Based on a fair bit of experience in these types of things (unskilled individual doing skilled trade work around various homes/rentals etc), anyone who's capable of doing these types of things while supervised via facetime is probably just as capable of and willing to do them with a youtube or web tutorial.
Sometimes you have to sink a lot of time into finding the youtube videos that have useful information in them. I am always annoyed at the extremely high volume of low quality self help content on youtube. I think some kind of guarantee that you were going to get useful advice or it's free would go a long way.
