Im looking for a web app which a customer can log in, and upload dxf and dwg files and create a job. Once the job list is built they could select material, choose metric or imperial scaling. And quantity of the part. Once completed they can check out with stripe or paypal and estimate shipping.
Parameters such as max size and max thickness minimum features would dictate a successful upload.
There are softwares out there that do exactly this such as tempus tools. Id rather pay upfront for my own software instead of paying for third party
