Build an Online Store

Hi ,, I'm Looking to have one of the ready templates for an online shop (e.g. [login to view URL] ) and Customize it to my own business plan , Like to add some features to it and make it look like my own website , So The Project is Two parts : A)Finding the Closest Made template for what I need to be done , B) Add these features to it : 1- Costumer profile: a database to include at least Name, Address, Email, customer account, username and password, etc 2- Customer shopping history: In the costumer account to be able to see their current shopping cart, history of their last shopping and some recommendations based on their last orders 3- Items Data base: All grocery Items in superstore should be categorized and all items should have their specifications listed for each item (Weight, Volume , price range). These specifications would be used to restrict the orders based on certain weight limit or Volume limit. 4- Pup ups: During ordering process for all items, there should be some questions popping Up asking if the customer consent to the buyers to buy substitution items if the exact item was not in the store, Also the customer needs to agree and consent to leave stuff at the door if the customer is not at home at the time of delivery. 5- Credit card authorization: at the time of an order the customer has to authorize us to charge their credit card upon delivery. The charge will be made upon delivering the ordered items. The charged amount ill be the amount of Superstore receipt and our delivery fee,. 6- Confirmation emails: (a) Upon receiving an order and (b) Upon delivering the ordered items a confirmation email will be sent to the customer. 7- Store assignment: Based on the customer's address, each order will be sent to the assigned buyer at the assigned superstores which are the closest to the customer's location. 8- Website appearance: we would like a template that allows us to put our logo and name and other marketing Media like videos and etc. on it , We might not be able to run all these features at the beginning bit this is somehow all we though about. What we need is an estimation about the time and cost of preparing this website. from choosing the right template to adding all these features and make the site ready to run ,
