Outsourcing drafting

Hey guys, I own a millwork engineering business and was offered two dream subcontracts at nearly the same time. I'll have to outsource to make this work, so I can get somebody putting geometry into the Autocad files while I'm coordinating for submittals.

Anyone gone this route before? Currently looking into China/Philippines. I've worked with outsourced drafting before but never under my own umbrella. Any tips, preferred vendors, advice?

I plan on providing all documentation, floor plan CADS, detail geometry, and POSSIBLY dimensioning, as one client is extremely particular.

Thanks guys.
