Mobile devices friendly website development

I would like to build a website with an application for my auto title loan business. The customer would pull up to my appraisal partners retail location and fill out the applicaiton as described in step 1 below. When the customer submits the application it would then go to the store front attendant that would complete step 2. Step 3/Backend Flow is an integration into the CRM that we would use. Step 4/Store Administration refers to my ability to go in and add new retail partners to that can appraise cars for me. 1. Customer Flow a. Customer visits the stores unique URL in their browser. (Could utilize QR codes on posted signage.) b. Completes application c. Submits application d. An email is sent to the store with a unique link to open the existing application. 2. Store Flow a. The store employee will click the link that was emailed to open the customer's application. b. Verify/edit application information. c. Upload images to application. d. Change application status to "completed". e. Click "Save" 3. Backend Flow a. When an application status is changed to "completed" the system will send all data and images to the Infinity Eclipse API. (API to be provided after I select a contractor) 4. Store Administration a. A hidden store administration page will be accessible via a single username/password authentication system. b. This page will allow an administrator to add a new store to the system and enter the email application links should be sent too. c. When a new store is added that stores unique URL will be generated. If, you understand the project than send a detailed proposal and best will be selected.
