you're in a rich area so if that is your target market you have to have "value". You don't want to appear cheap, as other posts have indicated. KNow your equipment and how to use it. If you're going to do it right, get a vacuum as well. Take your time and charge enough that you can take your time. Work out ALL your expenses and charge enough to make a profit. Your prices do look low, easier to start with a little higher price (based on my own hindsight) than have to raise your prices later. Rich people will pay but they want good value for their buck adn they want to know they are not being ripped off. Be consistent, by the room or by square foot. You can either adjust the price for traffic areas or figure out actual cleanable sf.

AS a newbie you need to get your look down, cards, invoices, fridge magnets, info sheets, etc, all having the same look as if you were a franchise. You can do that from your own computer at first.
Have a uniform, if only work pants and an embroidered shirt with your name and company name on it. Embroidery shows more "permanence".
Having the rotovac equipment may give you an edge, give you something to market.
Pick up some sticky tabs, a lift buddy, styrofoam blocks, sliders.
2 good pumpup sprayers/battery sprayer, 2 grooming brushes, one for prespray and one for protectant
