DAVID GREEN: Hi. My name is David Green with ExpertVillage.com, and I will talk a little bit about pricing out our job. As far as for our company, we primarily price by the room. There are variations of that where we have; if a room is smaller than a certain size, we will consider it a half-room or if it's larger than a certain size, we will considerate it as more than one room; and then we do room specials. What's ideal about this is you can price out most jobs over the phone without having to go out and give an estimate. The other option, of course, that a lot of companies do is square footage pricing where they're actually measuring everything. As far as--with this room, it's a fairly large bedroom but, of course, we just would just price this as one room. We then price hallways by the linear foot to where we measure the length and times that by our rate. Stairs, we price per step. So for us, the only times we're really measuring, we'll come in with a measuring stick that rolls along the carpet. We will use that to determine if a room is smaller than a normal room or larger than a normal room, or, like I said, the length of hallways. And then we have a per-room price for our products like sanitizer or carpet protector. And there's quite a few services that you can get into as you provide a quality service in a thorough service or--when you really get into all of the things that customers might be in need of to fix certain circumstances or special cleaning needs. And the best way to do that is to implement a price guidance. With us, between all these services, between carpets and upholstery, we've got two pages of prices, then we get into about a half page of tile cleaning, half page of air duct cleaning, and about a page of window--about a page and a half between window and blind cleaning. And what you ultimately have to do is figure out what works best for your market as well as what works best for you, 'cause pretty much in any market, they're going to probably price things out both ways, depending on the company.
