My background: I am currently a graduate student pursuing my M.Sc. in mechanical engineering (already have my B.S.M.E). I currently teach multiple sections of "Introduction to Design for Engineers" at my university in which I teach solid modeling with SolidWorks. I can work from technical drawings or just description of ideas in order to meet your needs. I use SolidWorks in a lot of my work/research in order to make simple to advanced models. Let me know if you think I can help you in your modeling needs. Also, I can show some of my previous/current work if needed.
