Web App Full Stack (Front & Backened)

Currently, I am running virtual dating events online. The process currently includes: 1. Running Ads on Meta (Facebook/Instagram) 2. Leads land on a simple Tally form where they answer a few questions (https://tally.so/r/Zj5OOB) 3. The Tally form and answers are connected/synced to Airtable which keeps a record of ALL leads. 4. Those leads who have paid for the event, are manually marked as 'paid' on Airtable and automatically moved to the 'conversion' Table. Note: Leads are considered as those who have submitted the form Conversions are considered those who have paid for the event. 5. I then manually assign them a group and send them emails with event details and instructions. Now i am transitioning into a proper landing page with an integrated form/questionnair when they click on the CTA - see link below: https://www.figma.com/design/YgcqkfQB6CltwL7WV4nEyl/Solonect?node-id=0-1&t=wat3euuDDLhzPjUB-1 What I am looking for? To implement the front end design, and ensure the backend is also integrated so that all leads and their answers are inegrated into Airtable just as they currently do. In addition, i am now trying to implement subscriptions, so accounts will be created (linked to their email) and the backened which is Airtable will need to manage this depending on the type of subscription they have bought. In other words, how many events they can attend per month. If this is something that is within your capabilities, then i am happy to go on call and give a tour of the current backened, which i want to keep the same but integrate with the new landing page/form.
