Where to find K20C1 CAD Model?

I am trying to find an accurate model or STEP file, that is SolidWorks compatible, of a Honda K20C1 engine (with manual transmission preferably) from a FK8 Civic Type R for use on an upcoming project. I would be willing to pay for the model as I do not expect anyone to do something for free. The more thorough & complete the model, the more I would be willing to pay for a copy of it. If anyone is up to the challenge, please let me know what your price might be. If anyone knows something more than I could find on google (nothing) that already exists, that would be wonderful, also. Thanks everyone in advance for even entertaining this post.
