You could try BlueHost service , I've been using it a while now. Works very well, as it has IPB and phpBB2. Also has unlimited bandwith, hosts blogs, forums, message boards, ect.. You should try it.
As an experienced webmaster I recommend BlueHost service which I’m sure it would work for you and fulfill all your requirements. They have a really great offer for hosting & I have used them for over 3 yrs now, and have never had a single problem with them.
