Webmaster Businesses

I'm thinking of getting a little extra money by starting a small internet webmaster business. I would like some information about webmaster businesses, especially if you run one (I'm talking very small, such as a one person business run from your house). Anyway, these are my questions:

1. Do most places use PHP, CGI, C/C++, or all (I would guess only one or two.)

2. What do most Webmasters charge (by hour usually) and about how long does a 5-15 page site usually take to do?

3. Do most webmasters use Javascript (I'm guessing yes) and Flash?

4. Does anyone have a site for a small webmaster business, or even a site with non-free templates.

Thanks all (and no, this is most definetely not for a school) :D .
