Launching a new product as a student
In terms of quality and reliability, you cannot beat machine placement on professionally manufactured PCBs. 

You will most likely find that option #2 + #3 will work best - get the PCBs made offshore by a reputable low-cost shop that deals in prototype volumes (which may or may not be easy) and shop around for contract assembly places.

Have you considered sourcing the parts yourself (i.e. issuing a complete parts + boards kit to prospective builders) or are you looking for someone to supply parts as part of the service?
