Modular Synth Panels

I am doing a set of VCS3 panels.  I am not using fpd for this rather I
am going to try Metalphoto of Cincinnati.  I have a computer drawing
that I've done (pft..) and lots of photos  readable close ups and a
sample panel that is the right dimensions with the proper punches, but
save for hand drawn instructions is blank.  They have an art
department and I am paying a $75 per panel art charge.

Having no experience except with Shaeffer, do I have enough to give
them for them to make an accurate drop in replacement ?  What else
should I do ?

I really am a novice and I need help from this group.

thanks
