Engineer a basic web based 2D CAD system.

Description

I'm seeking an engineer to develop a basic web-based 2D CAD system.
- I would like people to be able to log in and use the tool via the web, in the web browser. So we can support both Mac/Windows users.
- The 2D CAD system will be made for leathermakers. Leathermakers will want to design guides and templates for their products. To be exported into laser and CNC cutting machines.
- The user interface will be super useful and user-friendly (I'm a product designer by trade and can design such software)
- I would like the software to offer a catalogue of materials/tools to order within the web app. These orders will be processed and order sent to supplier.
- I would like the software to house learning material, such as tutorials of making leather products, using tools and how to use the software.
- I would also like Leathercrafters to be able to design their design studios. For example, a birdseye view of a room, calculated in sq meters, shows desks, work benches, and machines. These items can be dragged and dropped around the room as the user pleases. This will be in a very basic way, only showing outlines of the room and items.
I like simplicity in software and companies like 'Figma' is a good example.
However, another tool for inspiration on the market that already offers fundamental features is called 'LeaterhcraftCAD'. Please read what if offers: https://coffee-craft.net/en/leathercraft_cad
Based on the information I have provided, please give me ballpark prices/timeframe.
Thanks,Andrew
