Build a Website

We are looking for a company to create a website for our new business, which is an Estate Agent and Letting Agent. We would like a responsive site. We require 15 pages, with a further 80 location pages that will be the same but with a different photo and very small amendment to the text. The pages will include a Contact page and we would like a Live Chat pop up as well. We would like to be able to make amendments to the text within the site ourselves. The site will be linked to a CRM which we are going to become members of and will have a search facility of the properties. One of the pages on the site will have a sliding bar that will calculate the saving that the user will make if they use our company against the average other companies. The rest of the pages will be quite straight forward pages We will provide a logo and drawings of the layout of each page. Can you please give me a quote for this work and tell me when you can start and how long it will take you.
