Don't go for cheap overselling, if you're going to host a serious site.

I think the price you're trying to set for that much resource is a bit unreasonable.

Below are the companies can provide you 40g disk space
BlueHost, IXWebHosting, iPower, Aplus.Net, iPowWeb.
And they are all very reputed companies, and 40G disk space is included in their most popular plan, so you can try them.

Make a search in the offer section for your budget specification. Are you still in the same budget to deal with the hosting provider? You might get an host in the offer section (in other forum also), according to your requirement with low budget.
Good luck

try www.hostinput.com they are very developer friendly and offer custom plans.
