Add more products to existing Angular.js Online ordering page

I currently have an application that is an online ordering page for a signs company. The user is able to generate a shopping cart of their sign design (material, finish, text, mounting..etc). They are able to see a preview of the sign on the screen as well. The user can then save the order and come back and checkout at a later time or purchase the order at that given time. You can view the existing functionality of the site here: https://signbuilder.impactsigns.com. There is currently 2 products the existing site can handle, Metal Letters and Cast Letters. The requirements are to now add support for 4 more products Formed Plastic Letters Fabricated Stainless Steel Metal Letters Cut Acrylic Letters Acrylic with Metal Laminate See attached document for more details on the options for each product. The system is setup to dynamically load the product options from the database. The main chunk of work will be building out the angular modules for each new product and any custom rules, html rendering..etc. If you view the source code of the site you will see all the angular.js files and how it is setup. The backend is C# with Web API with SQL database. Need someone with angular.js skills and and some C# experience. I will be handling most of the database type work myself. Looking for ONLY local resources in USA. Please do not bid if you are overseas. Let me know if you have any questions.
