"As for the mike problems.... too much fancy equipment that I don't know how to use"

All you need is a good sound feed... ooooo there's a song in that...

You can use those cheapie desktop PC mimost noise any greater distance than the head so you won't get instrument pickup very well.

You CAN use any complex system of mic and preamps to feed any mixed sound in - I have heard entire groups 'live' on paltalk - you just have to get the correct technical matching on the input.
