Yes, the non-text portion of this message was removed, but so was the

Trying again:

If they purchase the parts, they will charge you for their time, as  
well as the cost of the money.

They will charge you for programming the pick-place machine

They will charge you for the solder screen, if they do that (that is  
somewhat expensive) or the cost of programming a solder past  
application machine.

They may require some DFM rule checking before the board is ordered  
and will charge you for that.

If they order the boards, they will charge you the cost of the money,  
again.

If you want to get a handle on the NRE vs per unit, also get an  
esiimate for 1K. Almost all of the increment will be per unit assembly  
cost., You can use that and the original estimate to figure the  
effective NRE you are being charged.
