cwhois shopping cart customization

1) I need a cwhois customization in terms of that the script is looking at a own whois database to check avaialabilty of domains. 2) There needs to be a new product to be added to the shopping cart (whois data protection) which the customer can select so in the whois search it will be not visible who is the owner of the domain. 3) Furthermore there are premium domains where the cwhois script needs to recognize the higher special price and add this custom price to the cart. 4) There needs to be an option for users to make an account directly in the cwhois cart when they checkout (username/pass) so the domains are assigned to an account in mysql 5)Last, the bought domains need to be entered into the mysql database with the customers details.
