Selling my services. I'm a Mechanical Designer and proficient with Solidworks. In the past, I've taken these 1 page speaker plans and created multiple page plans from them. Each part of an enclosure per page. I've got 5 or 6 differnt cabinates already done (Mostly EV Cabs). I charge $15 to recreate/clarify/simplify existing plans. I can also formalize your designs as well. If it's your design and you don't care about it being proprietary, I'll do it for $15. If it's proprietary (you want to build and sell your design and don't want anybody else selling it), we'll discuss a price.
