There should be nothing wrong with QFP for a real manufacturer.  However,
that brings up the question of whether you have designed this with
manufacturing in mind.

Do the thru hole parts really need to be thru hole?  Realize that this will
cost more and add process steps.  Are your board drawings, location index,
BOM, etc all ready to go?  Are there fiducials in at least two opposite
corners?  How is the manufacturer going to test the boards?  Do you have a
test jig?  How will all the programmable parts be programmed?  The procedur=
e
may be obvious to you, but it needs to be spelled out in detail, preferably
with pictures, so that someone that can't spell "PIC" can do it.  If this
requires specific hardware and software (PIC programmer, cable, PIC
programmer app), you have to supply this and specify what kind of machine i=
t
needs to be run on, how to install it, etc.

Putting together the manufacturing documentation can be significant work,
but it's just another part of the overall product development process just
like designing the schematic and routing the board are.
