Web development

I need a new website. I need you to design and build my online store. I am not computer savy so I'll use lay man terms. I want an Ecommerce website like Amazon or Ebay but not too complex. My budget is not fixed but I want a fixed quote. ThanksBUYER SIDE -Log-in / Sign-up via email -User’s settings (change email/password, notification settings) -Personal profile information (bought items history, likes, email, adress etc) -Notifications system to email/text -search items/category/filter/ view specific seller listings -Make purchases with card or Mpesa transactions -Choose delivery address -Send order requests, communicate about these requests (via messages) SELLERS  SIDE: -Manage personal profile information like buyer -Creat listings/ View listings -View transactions history. LISTING -Provide item picture -Description box -location of item -price -message box for inquiring on the item -similar items area -Add to wish list or like button -Add to cart button VISION I want a website that is similar but not too complex like Ebay/Amazon. A site where sellers can sell items by posting on site. Where buyers can easily find items they are looking for. Notification are sent to both buyer and seller once an item is bought. The site should also be mobile friendly and easy to navigate. The host (I) can also post listings for buyer instead of buyers if it will make the site easier to construct. Transactions will be to the host directly not seller.
