API Integration for Domain Registration and Management - on Wordpress.

We are setting up a website for services related to just 1 domain extension (for e.g. .ME). We have more or less created the content for the site. We would prefer it to be made on WORDPRESS as our site is hosted on Wordpress platform itself. We need the following : USER SITE 1. On the search page/bar, the domain name's availibility to be checked. 2. If domain is available then customers adds it to the cart. 3. If domain is not generally available at the registry's end but available with us as a premium domain, the premium domain with high pricing is listed. 4. At the Checkout page, either he logs in to this id or registers himself if he is a new user. 5. After registering he is taken to the Payment Page where he pays. 6. Payment Gateway Integration (either DirecPay or CCAvenue) for making payment. ADMIN 1. An admin panel needs to be created for complete management of the domain system - new registrations, renewals, reminders, billing/invoice system, support system (ZenDesk integration if possible). 2. Payment reminder for people who showed interest in a domain but did not pay, or for people to pay and renew the domains. We are selling domains as a Reseller with a US based ICANN Accredited Company. We have the API Codes which needs to be integrated into our system for it to work. Since we are talking about just 1 domain extension and not hundreds of extensions which are in 99% sites, I feel it should take much less time and the work is not much. So accordingly quote. Most importantly - We want the work in MINIMUM TO MINIMUM time frame. If possible 2-3 days, because we have a strict deadline to follow. We have got a similar work done for a similar site so I know how much time it could possibly take. Basically I need to see how good is your technical staff and programmers in codes, modifying codes and scripts, modifying the site structure made on Wordpress or any other CMS. And the work should be neat and fine. Thanks & regards, Saurabh Dayal
