As some people have mentioned here, there are other issues to think of besides the IT aspect. There is employee training, risk assessment, policy development, and the business account agreements. Accountable is a company that focuses on these type of issues to make them easier by providing things like employee training, ready to use policies and procedures, and business association agreements. I found them while learning about HIPPA compliance, and I have not actually tried the product but it looks like it could be useful for you, so I thought I would mention it here.
