Need Help from an Engineer!

Hello,

Recently, I properly designed and modeled a desktop organizer and locker organizer. When I mean properly, I mean that I did the entire engineering design process (define problem, generate concepts, develop solution, construct and test prototype, evaluate solution, and present solution) using a engineering notebook and CAD drawings w/multi-views. What can I do after that? Where and how could I actually create my products? Would I need a patent, trademark, etc.? Thank you!
