Hello,
I am a programmer located in California, and have been working with DotNetNuke since it's first version.
I have released a few commercial modules, as well as developed and modified modules on a per-client basis.
I can duplicate your site in DNN 4.4.0, and set it up on my staging server for us to review. Once complete, I can setup the site on your hosting-server (or in-house-server) - provided I can get remote access to this.
