Welcome aboard, olganeex,
I moved your topic here, where it's place most probably is, so it will most probably find an answer.
Of course you guess that I will tell you that Astahost is the best solution, because it's my own choice.
More seriously speaking, I think you have to choose the best price/performance ratio for the usage you want. You should mainly target an easy-to-evolute solution. Start small, with a reasonable disk space, and look how many visitors you will have and how fast you will exhaust a standard storage place and a storage monthly bandwidth. What I like with Xisto is that you can start small and grow, simply simply asking for more space or more bandwidth.
And, if you are unlucky and don't have a lot of visitors at the beginning, there is no reason for paying for a lot of bandwidth if your visitors are few.
So, start reasonably, find a nice design for your site, let your users come and let your site grow and ask your provider to let your account disk space and network bandwidth grow accordingly.
