I would be happy to pay a little to get free users. Once I felt ready, I was planning on just calling mobile auto detailing businesses up and trying to get them to let me demo to application. I own a mobile auto detailing business myself, so I hope maybe I won't get blown off as much as normal because of the common ground.

The brushing capability took me 3 days to implement. I did it in sort of a "manic" phase of productivity. I like the way it looks, but I feel like I burnt too many cognitive resources on something that should have just been implemented in a "good enough" way. Not sure if that tidbit is interesting?...
