What does this woment bring to the table? Not much from the sound of it. She does not even speak english

That's not good. It leaves you with having to do all the talking to customers, all the time.
As a busines owner my advice would be the same as everyone else, a big NO.
Sounds like you have a solid plan for this business. Ask yourself, do I really need a business partner? Chances are you don't if you have all the skills and resources to do this on your own.
Good luck
