Anybody here code iPad as a hobby?

For any of you that code as a side gig or hobby, I may have a project that can turn in to some royalty money.

I want to make a very simple version of a CAD app. All the apps in the store are overpowered for what I want, and as a result way over budget... or just suck to begin with.

The problem is that I have a couple hundred iPads that would need access, but for only very limited function. All I need to do is draw simple outlines of house floorplans, run simple calculations, and export to png and dxf. An in-house CAD app would eliminate the licensing cost of the big apps, and I can pay a small percentage of revenue royalties as a result. Win-win.

If anybody is interested or know someone good that would be, chime in
