That sounds cool. I've also looked into this business model.
How far along are you? Did you validate the concept yet?
I'd highly recommend setting up a landing page with the pitch and benefits outlined and then building up your pre-launch list. I actually have a background in web design and startup marketing (https://www.cameronroe.com) It would be interesting to hear your plans about marketing and see if you needed some extra help.
If you want, let's set up a time to chat. I'm actually looking into re-locating to Barcelona.
