Hi,Greetings, please read entire message and decide wisely, I'm not sure what other competitors bidding for this, but as We have worked on GPS integration, tracking, rating, messaging related apps & know how much time we do need,how many dedicated resources to be deputed for its execution within agreed time hence budget matters, have trust in my words, skills and commitment for its quality delivery.
I'll depute senior PHP developer to design and write database, webservices API and web dashboard so that you can manage customers, content within the app, senior UI designer, one associate and one senior ios developer to assist, in the last 3-4 weeks testing associate, team leader and project manager (me) will be in touch with you most of the time and this project will take 3 months minimum time to deliver.
features of app: two type of users (end-user, agents), agents will be listed based on GPS, end-user will lodge complain with details, agent/you will collect and process it further and send notification to execute the task and ask time, payment either cash on delivery or online, rate on to each other and communicate via messaging (simple messaging I'll get implemented not using any protocol like whatsapp) and web admin to manage both users, orders, payments, rating etc.
prior to confirmation on everything I would like to discuss each screen, web admin functionality and database once with you.
kindly initiate a chat, portfolio I'll show during chat, so lets finalize it.
