I am looking to have a website designed that has the same functionality as buybackworld.com's website. Selectable menus that end in the user receving a pre designated quote for their item. 1. I want it to be extremely similar without copyright infringing. How much would have to change? 2. Can the web designer just use 90% of the code of that website? Wouldn't this drastically cut down the price of such a website? 3. How hard would it be for me to edit the website to add products and change prices? No web experience besides shopify/ebay. 4. Would somebody on fiverr or something be able to put together a cheap site with maybe 5 products for testing? 5. How do I test how hard a keyword is to rank for? Optimal keywords would be like "trade in iphone" or "upgrade iphone". I'm not looking to spend more then a few hundered right now, I want to test the business model first.
