Unreal Engine 4 - Programming Oddjobs

My team and I are currently developing a mobile VR experience using Unreal Engine 4. For the project there are various components that are outside the scope of our own developers and will need the help of others to get the project finished in a timely manner. We are looking for staff that are trustworthy and that can be taken in as a part of our team as freelancers that we can go back to, should we require any more services. This is more akin to a test job to try and find these people. The listing calls for C++ programming as Freelancer doesn't have a category for Blueprint programming. Blueprint, however, is what is being used and what will be required. The details for one of the odd jobs we need is in a document attached to this listing.
