Yes, we'd like to get you up and running. 

I should be able to give you an alpha release in a week or so. There are some 
performance issues for a site as large as yours. I assume that will take 
another month or so to get a production-worthy version done. Does that time 
frame work for you?

Especially for GRIB files, you likely need this new "Forecast Model Run Collection Aggregation" capability. We have been working with our IDD NCEP GRIB files, and there are some complications, especially non-homogenaity due to missing records and variable time and vertical dimensions, that cant really be solved by the current (index based) aggregation. 

Ethan and I will work closely with you guys to get this working. I'd like to 
understand what you have in more detail, number and types of files, how they 
are stored, etc. Can you or someone summarize?
