Software Development

What I'm looking for is a CRM and Business Application system all into one system dash board set-up where you have tabs listed ( Print Contract, Print Invoice, Print Receit, Upload or Edit Listing, Welcome Letter, Work Sheet, Leads,Track Leads, Import Leads, Tracking customer sales stage of deal. It has to be web base hosted. We have a website WWW.VACATIONREALTYGROUP.COM. I need to build a system where we can add property listings where I can use a template with drop down boxes of property details to add them to the data base of the listing that we have instead of manually adding each one. Creating functionality to do mass emailing based on the contact list in your database or a purchased list of potential customers. What would be the cost and how long would it take? Thanks Jack
