Remake a company and Product catalog page

We had postnuke (then named Zikula) for CMS with a custom product list module. The custom module was administrating all the products we sell, and the cms was administrating the blog and news. We have a product page, and also on the backend we had a quotation module (the visitor selected the products he wanted us to quote, and then our staff adminstrates and sends the quotations). This module was able to admin and add products, solutions, brands, prices, categories, tags, etc... Now zikula is obsolete, and we want to move to wordpress. The webpage we currently have is [login to view URL] We need: - To migrate all (Zikula CMS) to a Wordpress with a cusom product module (as the one we have now). Maybe using woocommerce or whatever you recommend to have the same we have now. - Add a solutions page like: [login to view URL] where we will only post solutions instead a products. - Move all the actual product database to the new module with images and attached files. - Respect the same data scructure we have now. You have to navigate the hole page in order to understand. - Have a search function on the product module. - The actual product module, saves the products a new lead wants, with all the lead information (name, phone, message, etc). Instead of saving this information we want it to be sent to SALESFORCE to follow the sale. - We made a draft of the design we want, it is attached to here (the image below). We want to follow this mixed with a responsive theme. We have selected some that have also product calalog schema, these are the themes: [login to view URL] [login to view URL] [login to view URL] [login to view URL] The Add products to quote, will need to work as: 1. The user browse and selects (clicks on "add to my quotation list" buttons) on all product he is interested. 2. After the user is done selecting he can click on a "send to Altatec for quoting". Where he can review the list of products to quote, remove products, print the page, and there he can change the product quantities to quote and also add comments to the request. 3. The user have a contact details form he need to fill The title, name, lastname, company, email, phone with lada, are required as optional info with a "this information will help us give you a better service" legend: adress, city, state, zip code, country, website 4. The quotation will be saved on the database but also sent to [login to view URL] Related products, product lines, and articles for a Product. The product page has a "people who bought this also boughts" and then the list of related products. We need: - To be able to relate product lines - To be able to relate products - To be able to relate articles (the ones on wordpress). This is very important because we will be writing client testimonials, product news, product guides.
