Yes and no.  We have a setup fee and just charge time and material for the part.  If you order 1 part that cost $5.00 to make you pay $5.00 plus the setup fee.  If you order 100 parts you can amortize the setup fee over a 100 part so the per part cost is much lower.  We do offer price breaks on both time and material if the order gets very large do to the fact we can order material in bulk.  We also offer a service call down time services.  If you have a part or product you need a constant supply of and are not in a hurry we will just keep you job in cue and cut when the machine has a gap in jobs (down time).  For this service we do not charge a setup fee everytime we run a small batch.
