Anyone else do/doing DE with CCRM?

I have my ODWU in a few weeks but noticed that their donor pool is pretty small. Does anyone know how long it takes to get a match with them? It seems they'd "prefer" you use their donors otherwise we get caught paying lots of extra fees like the ODWU for the donor from an agency + agency fees, etc. But at the same time, with the available donors they have, it seems like it could be a really long time for someone to come along. Looking for some reassurance or some guidance.
