hi all. recently got the request to arrange and record guitars for a whole album (9 tracks). thing is, i don't really know the guy and at first it seemed like he was asking a favor, just general advice, which then grew into this whole painstaking process. i'm by no means a professional sessionplayer, but i know my way around pop/rock production and arrangements plus i got some nice guitars and amps which per se are a value for the "client". i honestly don't like his songs, so i thought i could ask for payment. what would you charge per song in this kind of scenario? one song will probably take between 3 and 6 hours of work.
