I need help with the design of a circuit board along with parts sourcing.

I need to make several single channel Microphone preamps with 48 volt phantom power inexpensively.

I would like to work with someone to map the circuit board for production.

Pre Amp is for semiprofessional audio use (XLR input - Line Level output)

Help needed fast.

Thank you

I need help with your request.

Physical size limits on pc board?

Power availability / requirements? Batteries/AC/DC/unipolar/bipolar/clean/dirty?

Location? Inside a mixing console, stand-alone at a truck rally, oceanfront - ?

Several channels on on board, or several single-channel boards?

Equalization / bandwidth / rolloffs?

This is all great everyone though I'm actually needing help designing the board with components. I'm willing to pay for the assistance. What I need is to possibly speak with someone here and go over exactly what I'm needing for a finished product. Let me know if your interested.

Thank you
