Changes to WordPress Website

Description

We have an existing website www.adegrity.com. It focuses on providing services to our commercial clients. Clients ring us or fill in an enquiry form.
We would like to add our domestic services to the website and custom ordering.
The site would be split into 2 sections domestic and commercial services. We require some services removed from the commercial pages, content changes and maybe design tweaks.
The domestic side needs to be set up entirely. Our domestic services need to be added and a custom ordering system implemented that is based on your postcode. Client inputs postcode and the different services are displayed with a price, client can click on the service or combined services they want and order. Client completes the required information we need and they are given the option of selecting three different date and times for their appointment and then pay for the service using Stripe. An order email goes out to us and client with the information.
We would in the future like to add further functionality for clients, so that has to be considered at this stage.
We will supply wording, services to be added, Stripe account, etc.
You must be experienced in developing services and custom ordering on WordPress. Please do not complete any of our enquiry fields or telephone us in relation to this project.
