Convert Wordpress ongoing plugin to Drupal - Car Rental System

Hayo DeveloperS!
How many of you tried to use Agreservation module to implement rental systems on Drupal without success?

FIRST OF ALL, this WILL be for commercial usage and we are working to have ALL needed functionalities to manage a multi rental car system.

Me and some developers have been working on a wordpress plugin to achieve this deal, IN THE RIGHT WAY, and, as a Drupal evangelist, i must say i hate to be doing this for Wordpress....

I already have a 2 year worth project done, let me tell you about the features:
- Renting system for multiple car rental companies
- Branches (each car rental company with its places and available hours)
- Fleets (Each fleet that belongs for related branch, and with its price scheme)
- Extras (Control over the extras each fleet has, like AC, Electric Locks and so on)
- Price Schemes (Create multiple price schemes for fleets and extras, this is the biggest one, because we have day or hour based prices, prices variation for longer rentals and so on)
- Languages (Structure to make it a multi language ready solution)
- Reports (with commissioning for finished reservations)

Some tasks left to be done::
- Company and user signups/fields with appropriate permissions
- Some emailing actions upon progress of reservations
- Many minor improvements for the navigation, mobile and overall usage
- Make everything translatable.

I intend to put a large portion of the code for Drupal community as a module, but some premium features will be commercial only.

Are you up for the project
I'm a very open minded guy, and i'm willing to negotiate in many ways, i can let you use the code if you want to volunteer or i can pay you for your time after project is done.

Let's talk!
