Build an Online Store

I need to setup the "cart" on eBay to accept 1lb of any flavor for 23.99, 2lb of any flavor combination for 21.99, 3lb of any flavor combination for 19.99, 4lb of any flavor combination for 17.99 and 5lb and over for 15.99. I think shipping is a flat rate of 4.95 USA for all bags and each sample, unless you advise otherwise. I also would like to have SEO optimized, other recommendations and automate the whole process eBay. I also need "variants" to have many auctions going at the same time (where 1lb of any flavor is for 23.99, 23.98, 23.97, etc.) since eBay has duplicate rules. Finally, it seems that eBay won't show brands with apostrophes, can you fix this? Attached are examples of what I've done so far on eBay and the HTML insert. Also if you know Amazon, Shopify and other related sites, I'm interested in working with you immediately after if the eBay setup is successful. Finally, I have a wordpress site [login to view URL] that uses woocommerce to finish Woocommerce, PayPal, Wordpress Integration for the 4 products I described with existing FEDEX and USPS shipping tables, recurring billing, coupon codes, affiliate and themes. It would be nice to support the blog and shopping cart according to current website design. Beyond that, ongoing social media support and SEO... (I'm looking for a lifetime personality I can trust). eBay is the immediate 24 hour, I NEED IT YESTERDAY as a priority and proving ground... For less than $100. The rest is negotiable. The site [login to view URL]'s [login to view URL] is already built, we simply need it optimized for the cart, shipping and affiliate modules if you cannot do social media and SEO. We want to create an ongoing relationship. SEO and backlink ability is helpful. I also need to be taught how to manage these things; are you a good teacher? Please respond ASAP I need theebay site done right away. Also my SKYPE name is "robertbohen"
