Combo plan recordekeepers

I was wondering if anyone could provide the name of a dc recordkeeper only for a 401k/cash balance

combo plan for a small employer(< 20 participants) preferably not too pricey. Thank you.

I think all the major recordkeepers will do that. At least I've never seen one turn it down. Assuming someone else (TPA) is doing the actual admin on the combos. 

American Funds Recordkeeper Direct, Principal, Nationwide Transamerica, John Hancock, OneAmerica, Lincoln etc

The cash balance plan would typically have a single account, its own contract #. The 401(k) would have the regular recordkeeping for each individual participant (if participant directed).
