[Plugin: Request] Webhosting Plugin

Hello to all skilled wordpress plugin scripters… I am looking for a plugin that allows web hosters offer a domain whois checker and if domain is available they can proceed to checkout to buy. It should also include the option to choose a predefined hosting package, all within wordpress. At same time the checkout should include an order form requesting buyers registeration details.. then the details are sent to MySQL and finally buyer pays with paypal… other features sought is a widget along with it to allow the whois search be placed on sidebar, results are then sent to checkout page top proceed to order.

If you think this is a cool idea, check out free whois exmaples such as
