Julie, Are you asking if it's possible or if Tina can do this for you? If you are asking if it's possible to move a website from html or maybe Dreamweaver over to WordPress, then yes, I do that all the time for people.
If you have never used wordpress, I might suggest that you try starting a "test" blog at wordpress.com and make sure it's something you like and want to learn. It doesn't give you near the options as a self-hosted wordpress site, but you get the feel for it anyway.
I
WordPress myself.
