Mobile app -- 6

Hello! Can you give me an idea of Timeline and budget for an app I want to build on hybrid .. Essentially, we landed a permanent spot at a bar where we are hosting a "home base" event once a month. Instead of selling tickets for home base we want it to be on an app subscription membership. Customer downloads the app, it asks for their information and credit card, charges them a monthly fee of 8.99$ and that covers their admission to our home event. When they get to the event we can scan their QR code so we can track who is coming in our end. Would also have to give them the option to cancel if they want too. Is this something that is possible? Or is it super complicated? Also, at some point we would want to add our bigger pop-up speakeasy's to the app as well and have a second tier of subscription where you get a discount on the ticket price of our larger pop-up and can come to our "home base" events. Same concept though as above. So I would need a sign up page where users sign up and pick the subscription and add their card. The home page will show QR code and upcoming events they can add event to calendar and add QR code for their membership to the wallet on iOS (if not more expensive).. Also, 1 other screen that will be a settings which they can update their contact info, card info, cancel subscription or logout.
