I'm a student so this is no full-time job, but in the summer when it very well may be, I still can't afford a water tank and generator (unless purchased gently used). If I make enough to afford one, I would consider it. My clients so far haven't minded at all, like others said, showed me where the outlets were, etc. However, in the winter in WI here, no one has there hose out and hooked up (freezing) and all of my clients are heated garages. So I bring along a 6 gallon jug of water, which they find really nice. I would feel weird if in the winter I needed to ask them to fill it up in their house in their sink.
I fill it up, 4 gallons, with hot hot water at my house in the utility sink. Then when I arrive, I QEW right away. My very first client had (4) 1 gallon jugs of purified water and a bucket waiting for me...But from then on, I have used the jug. In the summer, like said before, I plan on using their water and electric.
Also, at Autopia or here (can't remember) somebody posted about "Professionals, yeah right!" type thing about hack detailers. That got me thinking about myself...I really haven't had any training officially (detail "school"), but yet I see myself as a better-than-average detailer (compared to those detailers I see in my area that have shops). I guess what I'm saying is if I'm one of those "Professional, yeah right" type people. I feel like the results I achieve are great though, on par with most people on the forums here. Would it be wise for me to get some training, though, just to say I'm officially qualified? I just don't want to be a hack detailer, but I do detail at autopian and detail city "standards," just no official training.....
