In terms of the interface itself, a number of UI elements are "jarring" with the client. It also feels like certain functionality is not working as expected. I'd be happy to provide an admin login if it helps, and go through things in a bit more detail via email.
You did not send contact e-mail. Also what exactly you would like to fix, I can do live support via team viewer or you can give me list of things to fix but I can not tell you hour rate on forum, send me e-mail please.
