Looking to tighten up some loose ends on our "Booksy" look a like app

I need some help tightening up the reservation process of our app. I need this done within 7 days. Basically, right now, customers can reserve a business on a flat rate but we want to offer variable pricing models. For example, cleaning for 45$/hr - > customer can choose how many hours and the price updates.

I’ve built this app from scratch and it’s nearly done, I’m just tired of working so hard on this part, willing to pay.

I also have another feature you can help me with.

Hey man, I know the struggle. Recently came abroad some time, so I’ll shoot you a DM and can show you what I’ve worked on.
