Build a service provider website similar to www.hellocasa.fr ......

I have a need for an ecommerce website where customers can search and view different services (electricity, plumbing, etc.) offered in their area. By filling in a form (most of them 3 to 5 questions by selecting drop-down or most sophisticated with images), a final price will be displayed. The customer then select the date and time using a calendar to book it. Then the customer can continue shopping for a new service or make the payment. The Service providers (who is in charge of updating his availabilities) gets an alert (dashboard, email, SMS) and do the work required.
