2. The OP makes the subject matter so enticing that somebody with the skills will drop what they are doing to make this happen.
or
3. The OP will learn the skill necessary to make this happen and get-er-done!
With the lack of positive responses, one must assume that the subject matter by itself is not enticing enough to attract modders to the project. So the next best option for the OP is to "make" the subject matter enticing which means using more than one short sentence as a description and asking if anyone is interested.
