Where can I find a driver developer for Win64 for outsourcing?

Question

Windows

The company develops all kinds of hardware. Including PCI/PXI boards. Until now, we use the product from jungo WinDriver which allows you to easily develop device drivers for Windows. Something like a framework.
So, they changed the licensing policy, now a separate license is needed for each type of board. It will cost us a round sum, which, moreover, will have to be paid with the release of each new OS.
We want to find a programmer who will write us the basis of a driver for a PCI device. In fact, we do not use all the functionality provided by the Israeli company's product. For example, they refused to handle interrupts on the bus.
In fact, you need to implement a dozen functions, such as allocation of physical memory on the 0th ring, access to PCI registers and resources, etc.
Cooperation options: outsourcing, fixed-term contract. You can also work permanently, but here you should not count on the salary of the market level, or even higher than the market, in contrast to temporary work. On a temporary or piecework can be discussed.
Actually - where to look for them?
Designers, translators, etc. full on different freelance sites, there you can see the portfolio, evaluate, give something to try ...
