I had someone like this a few years ago but they were asking for other little things they could help with. I found them some low-level yet important things they could do for us, made sure to thank them publicly in several places, and it was win-win. At no point did I give them user/pass somewhere nor did they receive elevated privileges anywhere; just something free for their time/effort. His motivation, had I asked him, was probably that he thought we were really small, really bright, and that he could save money with a creative solution to our problems. He was right and it worked out great. Good luck!
