Magento Extension Development

We are looking for expert magento expert to enhance the capability of pre-built extension Requirments We are using Amasty [login to view URL] extension which allows to create /setup dealers from backend, but it is not registering dealers. We like to have dealer registration from at frontend . Create a registration form (which will be entirely different than customer registeration ) for dealers and sales reps on frontend and link it with amasty extension. Once any dealer or sales rap registration received it needs approval process to approve or disapprove application. Once dealer or sales are being approved. Dealers or sales rap should be able to invite customers from backend with a referral code. (hidden in url) And if users registers with that link then it would be linked to the dealers customer group. if you need any further clarification please write in message. Thanks
