For your particular needs, I would recommend SurfSpeedy. They offer 50gb of space for only $6.99/month. If you pay for the year, the price drops down to only $5.99/month. They are a reliable hosting company with good service. www.surfspeedy.com.
What's the host you were thinking of going with? If you ask about them here, or better yet, run a search on their name here on the forum you should be able to get an idea of what their reputation is like (of course that's assuming people may have posted about them at some point).
