Hey There,
Greetings From S.I.S Technologies!!
As per my understandings, I can visualize your requirements to be somewhat similar to some of the leading online stores (Like Amazon, Flipkart, Snapdeal etc). The features/functionalities that makes it similar to the later mentioned are:
*Signup/Login through social media platforms.
*Online tracking of all the assets.
*Reviews/Rankings for every associated Buyer/Service Provider.
*Gallery to view all of the Product/Services available.
*Online Transactions (For that we can use PayPal, Skrill or Stripe)
As this are nothing but a rough Idea for all the features/functionalities that are needed to be incorporated in your required solution. But as to provide you with some final estimates (Including the Time and Cost), , I would like you to share all of your project related thoughts and Ideas with us. Possibly in the documented forms, as then it would be an easier task for both the parties to freeze on the requirements and stay on the same page throughout the project development.
Our Development Approach -
1. Freeze the requirements and create Information Architecture of the same. Define phases and milestones of the project.
2. Create and share wireframes
3. Getting started on the design concept after approval of wireframes.
4. Start with development activity.
5. Ongoing testing and share weekly updates
6. Beta release and after review/approval, final release of the webapp.
We can discuss further in PM.
Regards,
Ibrahim
