CAD Partner for Innovative Consumer Product

I’ve been working on an idea for a new consumer product for the last few months. I’ve got quite a long way with the idea but I’m going to be honest — I don’t really know what I’m doing when it comes to professional CAD! I’ve been trying to teach myself Fusion 360 and OpenSCAD as I go along... (Budget: £10 - £15 GBP, Jobs: 3D Modelling, 3D Printing, AutoCAD, CAD / SolidWorks, CAD/CAM, Fusion 360, Mechanical Design, OpenSCAD, Product Design, Solidworks)
