Did I understand it correctly, coin code (x11 + pos) was coded by a contractor, and "xcode" is coded by atcsecure?
Hiring a contractor to start your coin is ok in itself I guess, but what happens when you run into problems with the coin code and the contractor is fully booked for a week?
Do you seriously believe you need a "contractor" (how silly it sounds in this context) so that you can build on top of that your own implementation? It's money that is at stake, you need to control and understand the whole stack, you don't need anyone to do the ground work for you, if you do you are not capable of doing the rest yourself.
After all you want to be the first anonymous coin. With such a bold goal you should be able more than enough experienced to do everything yourself. No need for a "contractor".
