Replying to My big money-making idea

So I've been getting into waxing my own skis, and of course along with that comes doing it for my friends. I'll charge different amounts depending on how much I like the person and if I'm doing it to repay them for something. But I really like doing it and don't get to do it that often. So my idea is to make kind of my own quick waxing business. I'm in university, and I have a pickup truck, so I could either have people just drop their stuff of at my place and have it done in like 30 min or less, or drive to their place and just clamp their skis or board to the tailgate and do it right there. Do you think anybody would like this? Obviously prices would be a little less than christy's, or the same if I had to drive to their place.
