We use a real CPA (not a chain like H&R) and pay about $500/yr for our LLC returns. My guess is that H&R would probably be much less, but you will likely get a much lower level of personalized service.
If you are on a really on a budget, you also might consider doing your own returns. If you have some spare time and are confident with numbers, they really aren't all that hard to do. I use TaxAct (http://www.taxact.com/products/tastandard.html) to run different scenarios like it quite a bit.

We are in Virginia as well...one thing we do is trade off with the local CPA for services...No out of pocket costs for us and the local CPA has 2 websites...one for his business and a bed and breakfast him and his wife have on the side...been doing this for a few years and it is working out well for both parties
