Photography session booking and client gallery selection application

I run a small photography studio: I shoot portraits, families, newborns, sometimes commercial shoots. Right now everything is scattered across email conversations, a paper calendar, and a shared folder where clients get lost. I want one web application designed specifically for photographers that guides a client from their first booking to receiving finished photos. On the client side, they should see types of shoots and packages, choose a free date and time, make a deposit or full payment, and sign a simple shooting contract before meeting. On my side, I need a clear schedule with gaps between sessions so double-booking is technically impossible.

The most important part here is the selection gallery. After a shoot, I upload processed previews to a private gallery with watermarks tied to a specific client and session. The client logs in, marks the frames they like, and selects exactly as many photos as their package includes, with visible counters showing when too few or too many are selected. Comments on each frame for retouching wishes would be handy. Once the selection is locked, I retouch those frames and deliver the finals through a neat download section with full-resolution files and link expiration. It's important to separate selection from delivery: clients constantly confuse previews with finished work.

This is a tool for the photography niche specifically, not a general calendar or file archive. I want the booking—selection—delivery path to be convenient for non-technical clients on a phone.
