Website application to be built

Looking for someone who can create a web application for us. The purpose of the application is to compare pricing for various products/services. Clients must register on the website and manage their profile. They should also be able to upload products using an Excel spreadsheet if there are too many products to upload. The general public will then come to the website, do a search for what they are looking for and prices must be displayed so that they can compare costs. We will also require an admin role that will allow administrators to go in and access client profile info. Certain information must also be stored in a database, for us to generate reports or extract for further use. We would like to take a milestone payment approach: The system must be built to a certain point, we check it out and pay, and then the project can continue. We are looking at making around 4 milestone payments (Last payment to be made once everything is complete and signed off by us) *The website must include the following pages/menu options: Home, Register as a provider, Provider log-in, Resources, FAQ, Blog, Contact us *The resources page must allow users to download the items that we upload. *There are 4 types of services that providers will be able to register for. Depending on the service, the registration process may differ *We currently have an existing platform that is still in design phase - you can build on this or start from scratch *Website visitors must be able to conduct a search using various parameters on the front-end *The registration process will require confirmation emails to be sent to the relevant individuals *Tooltips will be required for various fields where users need to input data *Certain reports around stats and metrics will also be required *Certain fields will have to be validated before the user can continue with registration *We may require data to be fed to Mautic or VTiger at a later stage
