I opted to see if CCBill could install at the moment. They do CGI script installations for new clients, but If their is any DB integration installations done, you are respossable for installation (which I believe is what your looking for.) but they do have the abilities you describe.
We got put back at the back of the line because of some fine details not completed (they are very strict about having your site “completed” and if you just have one button no linked your in error of installation “readiness.”) So, still waiting to see if they are able to install on EE.
I would hope they are working on the backend with EE programmers on a nice module/plugin because both companies have a very large client base and both would benefit.
