minor fixes on a fully functioning wordpress ecommerce website

Website: [login to view URL] 1). basically, what I need fixed are the checkout section, I think the issue is, that the PayPal is not properly linked - It allows add to cart, it allows customers to enter their details but then, it does not give -payment option - It stops working after customers enter their shipping details 2). When you click on shop, it shows too many options with models, we want ours to show this page - [login to view URL] Explanation: I want to display two options (weave and clip-ins) and those two options are going to be linked to the two pictures in the gold frame on this page [login to view URL] ( I want us to link the pages to the images) - Then When you click on the images in gold frames, it will lead you to the color page which will be similar to our model page My ideal look will show models with the hair colour and when you place your cursor on the picture it will show the color block, reverse of what our model company did
