Where to start?

My husband is a professional photographer, schooled and everything. While blog hopping at some blog designing sites, a light bulb went off.  We had been trying to figure out a way to promote my husband's business and I though, why not make him a blog?  I don't know why this has never come to my mind before tonight. Maybe it was the blog hopping.

I wanted to put together something that would be a sort of an informational selling page. A place we can post his price list, portfolio pictures, contact info, you know important stuff.  I love blog designing and I think I really could do a great job on it.  If you haven't noticed, I've changed my blog look a few times in the past few months.  I have loved learning html and I think that I could definitely do a blog for him and help him to maintain it.  

What I am wondering is, where would I go to "purchase" certain graphics? I know I can't use freeware, after all, it would be for commercial use.  Does anyone know a good site that is not too expensive.  I really just want to be able to show what he does, what his prices are and what each package would include.  Nothing too big but, I do want to have some pretty graphics on the site.  Any help would be appreciated. Thanks everyone! Now, back to your regularly scheduled blog hop! :o)
