Hi there... Need a Wordpress blog huh? Do you already have a domain name you'd like to use with it?
Oh good. If you're already setup at GoDaddy then they have simple WordPress hosting for just a few dollars a month that you can add to your account.
If you're moving your domain from GoDaddy to another registrar I think you'll find your new registrar will also offer WordPress hosting at a modest fee (most registrars do these days). Take that into consideration while you're looking for a new registrar for your domain though. Even if the new registrar you want to use doesn't offer WordPress hosting, there are plenty of independent companies who do (not to mention wordpress.com itself). If you're keeping GoDaddy as your registrar and just moving your web hosting elsewhere you have many, many options (again, also including wordpress.com itself).
May I ask what limitation you're finding with GoDaddy? (I'm not suggesting you stay with GoDaddy, I'm only asking in case I have a solution to the limitation that you may not be aware of.)
