Our company is in search of a company in California that could provide check writing srvices for a client of ours. The checks would be on the client's retirees and the firm in California would need to handle the withholding and etc. Does anyone know of such a company located in California that could help us please?

There's a company called PenChecks in La Mesa (San Diego) that does just that. Phone is 619-462-7812.
