Welcome !! This is for you, some readings for new comers like you:

Then, follow these steps, and if something is going wrong, please, come back to us.
As someone who had the same goal–adding blogging capabilities to my web site as opposed to turning it INTO a blog–I can tell you that if you’ve managed to run your own web site for a while, you’re a lot smarter than you think!
And be prepared to change ISPs. Contact them, tell them what WP’s minimum requirements are, ask if they are capable of handling the software, and hope they tell you the truth!
Just for the record: ISP = internet service provider. The company that provides you the “wire” to be connected to the internet. Not to be confused with your host that is operating a server to host your website.
😉
Unless, of course, your ISP and host are one and the same, as with Earthlink, et al.
Absolutely you should go through the documenation and formulate a game plan. I was very annoyed about having to wait a week before I could join an ISP that worked with WordPress. But it turned out to be a blessing in disguise because I was able to spend that week going through the WP website, and equally important, doing some serious thinking about what I wanted to end up with.
May I suggest that you post a link to your current web site? That would be a good way to get some input into how blogging can make it work better.
