Have you ever dealt with fraud at any reasonable amount of scale? This is an absolutely _terrible_ idea.
The legal system will make sure the funds do not stay in your account.
However, it feels like this would be a struggle to keep up personally. Have you considered being hub instead, where others can announce their products, get paid for them while ensuring that customers get the support they need too?
Yes - my long term plan with the Libre Tech Shop is to also list products from other developers (especially in India), help them document these products and make them available here.
The idea is that once people know that if they want libre/liberated products that can run free/libre software reliably (and by default), they should be able to seek out all sorts of solutions for their needs from the same place.
Complying with their requirements could be a major headache (ask Purism), but if you're already satisfying all those, the certification and links might make business sense.
