saas taxy system app just like Easy taxi.

We looking a talented application developer(s) with excellent experience in navigation application, especially in taxi mobile applications, to develop our scalable and coded solid taxi application and dispatch system similar to Uber, MyTaxi, TaxiMobility and Liftago. The developer must be hard worker twith quality and perfectionist in their work equation.  Your will be responsible in design, development and deployment of the application, which is to be offered on a SaaS basis to customers. We assume you already have in hand a taxi script that can me upgraded/modified to meet our requirements. The detailed software requirements specifications included herein are very similar to those of the aforementioned taxi application, but we look to your experience to suggest any enhancements or functionality considered a must for inclusion.  The application will launch at a minimum with Apple and Android peripherals (mobile phones and tabs), but must be built on cross-platform technology to easily accommodate Microsoft and Blackberry devices, where deemed best option. We want taxi companies to sign up to the system on their own (self registration). This will allow us to limit direct sales and allow us to market the application globally in a very short space of time. Each taxi company will be able to have an account with us that: * on which credit is loaded (cash or credit card). Based on the billing method deployed, this balance will automatically be billed an amount deducted according, i.e. prepaid account, or; * A post paid account which can be paid automatically by credit card or cash deposit. In addition to the foregoing, we are looking for the application to be maintained and developed on an ongoing monthly retainer basis, including white labeling configuration from our customers. In this regard, please quote your price in respect of the maintenance and development separately to the initial building of the application, as the maintenance may, in fact, be done by us in-house. To win this bid you must provide example of any taxi applications you previously completed, i.e. previous experience required. I have detailed requirements, but will provide only to qualified vendors. Will have to send by comments/mail once NDA has been received. Once you have this, please provide your proposal response in a word/pdf document covering our SRS, any recommendation you propose, technology approach, costs and timelines.
