Would you like a delivery app that has all your delivery needs in one app?

So your monthly fee would cover grocery, restaurant. local store pick up..ETC Backstory: So I said I would build an app that i believe will solve a few problems in the delivery world. (Ex: uber eats, instacart...) So today I built the semi shell for the app and I have to say that I am impressed. I have never built an app before..Now to figure out what's next.. How do I get this idea out there? Please feel free to drop any comments or ideas!
