Yes, please come to NY. I would use this regularly.
Also, more insight regarding the materials your service utilizes (ie soaps, brushes, mits, wax, compound - if any, etc) would be great. If this is on the site already, I apologize, I did not register nor did I really dig around (Maybe I wanted to know a bit more to justify my time spent registering).
People dish out serious amounts to pamper their automobiles. Some take this very seriously and can be critical of the process.
Once established, there is plenty of room to both deepen and widen the product offering here - premium services: compound treatment for swirl marks, waxing, 3m clear bra, paintless dent removal, and so on.
I'm assuming you may be trying to create a labor network of sorts and started with basic car washes. Either way, I believe there is a market here, more details on the execution would be great.
*Provided these are hand washes and you're targeting a middle-upper class market, the price point is actually perfect. In my area (NY) I pay ~$30 for a hand wash, and I have to bring it in. I will not bring my car to a regular car wash, even so called "brushless" as they are terrible for your paint. If you're targeting the general public, it may be a bit high.
Given the whole, "we come to you", makes me think of washing the car in the office parking lot, which could indicate a White Collar demographic. I also see homes, but personally I'd just do it myself if I had a house and driveway.
One more question, how do you handle water at an office building?
