I had someone helping me out -- mostly updating paysites with content (making the thumbs, ftp'ing up the pics, updating the software, etc) -- but they weren't realiable enough.
When I had an actual person here helping me, he was more interested in using my fast connection to surf for pr0n than doing his job. He lasted just a few months
Pay depends on how you're paying them --- are they an employee where you take out taxes, are they an independant contractor who is supposed to pay their own taxes, or do you pay them under the table (next to the guy giving the bjs!)?
