Best web software to run a repair business

Hello Right now I am using a basic html website to post all my business listings surrounding every site near seattle.
I have about 50 google indexed pages on my site, when i have to update them it takes hours of going through them all.

Does anybody know any good cms software to run my local repair business in different states and citys?
I have googled alot and tryed alot of different website software but cant seem to find anything worth while.
Im a really bad writer so sorry for the lack of details, I dont really know what I need yet. any help would be greatly appreciated!

Wordpress.

That is all you need to scale up your website without the need to formatting every HTML codes. It really makes your life a lot easier.

Do remember though, you'd need to have a MySQL Database and your server running on php where it's unnecessary for a simple HTML site.

Make sure you 301 redirect all the old url's via htaccess if you choose to have a different url structure for the same pages. You can also do this easily with a simple plugin if you don't want to fiddle around the htaccess rules.

Feel free to PM me if you need any help in setting this up.

Thanks for the reply! Wordpress really doesnt want to get along with me. lol I guess its best to hammer away at it and get very familiar with it.
Doesnt wordpress install PHP and mysql automatically? very unfamiliar with them, going to start googling them now.
Ill just mirror my new wordpress site to the current tree of urls on my current site.

Blah I know i just asked typical noob questions.
Cant PM yet have skype?
