Another option is to hire Autonomous CAD to arrange the entire project for you. Once I have finished the details and you have decided that your ideas are starting to become reality I can take the rest of your project to my ever-growing list of suppliers to begin manufacturing your designs. You could have finished items shipped right to your door, or your customer's door, without having to source a single nut, bolt, wire, or piece of fabric. Your ideas to use or to market FASTER!
A big difference that you'll notice when you hire Autonomous CAD is that you will own the CAD files and drawings BEFORE working with a manufacturer. This means that you can shop around to find the best deals on whichever kind of manufacturing you need with YOUR CAD files and drawings in hand.
Even a simple sketch can be a great start to a project.
To really get things going quickly I can scan your project or even just the items that you need your idea to fit with. Then, with your input, CAD models and prints are created to communicate your designs to suppliers for manufacturing or prototyping.
