Anyone had this done? Recommendations for a company that can do a good job? I'm looking for a company that does the whole shebang, with recommendations, testing for leaks etc.. possibly even product recommendations for fixing issues.

Oh, and yes, I did use the search, I'm looking more for experiences.

Thanks folks.
