Use WooCommerce or Magento CE and MySQL to build a customized E-Commerce website with SEO. We provide printed circuit board (PCB) fabrication service (based on customer's design and specification), design service, and assembly service. The products and services are customizable or standard. Customer gets a quote by selecting specifications, quantity, and lead time for his product or look for standard prices if his product specifications is standard, then place order and pay. One analogy is that you already had a design of house, want to get a quote from us by imputing the size, selecting number of story, exterior material, interior wall material, roof material, floor material , etc., or look for our standard prices if your design is a standard product (different size but same standard materials), So the shopping cart will be different from most standard shopping carts for categorized products.
A good example of website for selling same products and services is: [login to view URL], but we will have less contents.
