创建在线店铺OPENCART最好

I need a website to start my online store I do not mind if you use wordpress,opencart,Zencart,Magento or other program. But it must be easy to use and include the addons if needed. I plan to sell wigs ,human hair wig and other kinds of wigs. I own VPS and domain Requests: [login to view URL] site must can send inquiry on product page and also can purchase on product page, I can get the inquiry both form dashboard of my website and from my mail. [login to view URL] site must easy to use and control. Can import products and add new products by Excel. [login to view URL] for SEO [login to view URL] BACK DOOR! P.S: Personal I'd like you use Opencart to finish the website(I use this for few month), if you have any better idea, you can also do what you want.
