Edit my Wordpress Site

I have a kitchen mediation website with the aim of bringing buyers and sellers closer to each other. The website is using Plug-ins SABAI, UPME and many more. Following changes are required On home page the buyer should have the option to provide the details about kitchen ([login to view URL]) what he wants to have, for example color, material, surface etc. The buyer must also provide all his contact details. All these details should be saved in database. The web admin should approve all these details and only on his approval the details will be visible on backend for the Kitchen Studios (Wholesalers). For Kitchen Studios (Wholesaler) there is a dictionary / record where all information like address, photos and opening timings etc are saved for each wholesaler. There are two types of subscriptions; one is free and one is paid. For paid subscription there are more fields for wholesaler. Once the web admin approves a buyer’s request, it is visible to all wholesalers. The wholesalers can see all details of buyers other than the contact details and address. The wholesalers must pay for each buyer to see his details. Wholesalers must have some credit in the website account and they can put money in the account any time. This credit will then be used to pay to the website in order to see buyer details. The wholesalers can sell model kitchens from their account. These model kitchens should be shown on a separate page, once the wholesaler has purchased an advertisement. One example of this model kitchen page is this [login to view URL] The example page for wholesaler is like that [login to view URL] The webpage has to be optimized, where needed and it should be SEO friendly. Everything should be automated and web admin should do minimum work to run the whole process
