Like others mentioned get a freelancer or an external team for starters. Engage them for 2 weeks. I run a dev agency. I recently made a chrome extension for a customer for the first time and it just took us 2 days instead of 2 weeks because we leveraged claude sonnet. So building a software today is incredibly easy, you can build almost anything at an incredible faster rate. So if you set 2 weeks engagement and you can see how much is done, you will know how to work with the person and team and also will be confident in your plan to move away from the software you're using. You could then have this team or freelancer document how this is setup etc and you can slowly start hiring in house. For eg, it costs like 800 USD for two weeks in our case since we are based out of India, so when you outsource to India, Vietnam etc you have low risk, you can quickly experiment instead of contemplating.
