Nice hosting plans, but to answer your question isn't possible, if your site is ready, you can see how much space it takes in your computer, as for traffic, its formula is the "weight " of the page * the approximate number of visits.

Hello. I suggest you start with small packages.

Those aren't bad but you may want to shop some more.

I think that type of site uses a good bit of bandwidth.

That type of site is probably going to require a large amount of bandwidth. How much? It will be hard to say until you get it going. Make sure the host makes it easy to upgrade your plan if you need to. This way you can start with a mid-size package and work your way up if you need to.

Good luck

Whatever host you go for, make sure you can easily upgrade your hosting as your site grows.
