Looking for a hydraulic systems supplier / integrator

I work for a company that supplies turn-key installations for a wide range of manufacturing customers, and am looking for a supplier who can work with us to design, supply, and install hydraulic units for lathe and mill fixtures.
We have several fixture houses that we partner with, but I really do not know of a company that specializes in hydraulic pumps, connections, sequencing, plc / direct-to-control integration.
Could someone please point me in the right direction?

Thanks.
