Booking script modification Codeigniter - Mod #3

We are looking for a professional but low budget CodeIgniter developer to perform the following modification to our existing Airbnb clone script: Enabling multiple bookings Currently a listing is created with the election of the provider how many people they can host. If a listing is setup for e.g. 10 people, and a customer makes a booking for less people, then the listing shows as "no availability". We want to enable multiple bookings for the same listing at the same date until the max. number of people allowed is reached. Here is an example: A listing is setup for a max. of 20 people. With the new mod, customers can make the following bookings (or similar) for the same day: 1 booking 2 people 1 booking 5 people 1 booking 1 person 1 booking 10 people 1 booking 2 people up to the max. people allowed. On the provider dashboard, each booking will be shown as a seperate booking, sorted by date and listing. Please also see our other projects, we have several mods for the same script. Payment policy: 1. We will create a full milestone payment upon project award 2. We will release the payment once 100% work was delivered to us 3. If one or more of the described items are not or only partially developed, then you agree to cancel the milestone payment entirely, seeing the project as failed in its' entirety with the reason that we will have to roll back in order to get someone else to redo the work. Please note we are working on a strict timeline, as other projects will be pending on the completion of this project.
