ok so a guy at our school, the theater manager, whom i work with frequently, and we help each other out with a bunch of stuff.( I help him run the tech aspect of shows and he helps me out by assisting me with outdoor parties that i DJ). anyway, he asks me if i woud be interested in doing his lawn for a few weeks while he repairs his mower (the spindles on a yard machines tractor went), he asked me to tell him the price and then just do it. since he is a friend and has a thin budget, would you charge differently? i was thinking that because we work together that i would just charge the cost of running the equipment. i am in uncharted waters for me, and was looking to see what you guys think. especialy BG.
