I need a moodle expert bad!

We have an installation running on a top dedicated server, our pages are slow to load , alot of extra files and system just runs sluggish. We have talked to server owner a dozen times and have been reassured the server is running properly yet we are slow as can be to load the first page after login. We need an expert to come in and re-do, re-organize and just get our moodle running right.
