SIMPLE Magento Login Customization

I am setting up a magento site - [login to view URL] we sell hair care and professional styling products (extensions, tools for putting extensions in women's hair) i want to sell our products to two types of clients. 1) GENERAL CONSUMER 2) PROFESSIONAL CLIENTS i need to create two different user types for log in to distinguish which items are shown to which user type. Simple to create the two different user types, however, i need to be able to manually approve PROFESSIONAL CLIENTS. this user type must be a LICENSED COSMETOLOGIST, SHOP OWNER, (OTHER TYPES -I will describe before we start project) and they will need to provide their LICENSE INFO to prove that they are a legitimate PROFESSIONAL user. From there it will send an email to my admin, she will confirm that the LICENSE INFO is valid and manually approve them as a PROFESSIONAL user. GENERAL USER types will be auto confirmed (default Magento registration) but will only have access to GENERAL USER PRODUCTS. [login to view URL] - see attached image for how i want this to look FOR PROFESSIONALS - on a page like [login to view URL] - we will add a drop down to ask what type of professional they are and for their license credentials... as described above this will not automatically create the account. Email to my admin - My admin will check credentials and make sure they are a valid PROFESSIONAL user. then manually approve account for PROFESSIONAL use. From there you will need to give me a basic tutorial on how to define which products are shown to GENERAL users and which products are shown to PROFESSIONAL users when i add new products. Some products will be the same but price will be different depending on GENERAL or PROFESSIONAL user level. My Budget is $100.
