The first thing is first. Many people would like to start a business AND get support from devs/staff to make their dream possible. i.e. some people want a tech store and therefore require devs to implement a store for you to use. I would recommend that you do ( for now) independently run a business out of your house/car and start selling tech that way. If you can create RP that all parties involved can enjoy, you can probably have a look into how you can 'officially' request for yourself to receive a full-blown tech store.
I hope this helped!
