Build an Online Store

I have to develop a web portal for 3D printing services were individual user and service provider can interact together. Each service provider will register their own and also the users. User can find the service provider based on the local preference (means locally residing service provider in an around of 25km). Once user will upload a file he will get the rates of all locally registered printing service providers as per their rates given based on per hour basis or volume basic or other parameters. User will select the service provider as per their wish, then message and email will sent to that particular service provider, he can accept or deny the order, once he accepted then user have to pay the total amount in advance. Once user have paid the amount message and email will go the service provider then he will start printing of that part. Once it get printed then further message will come to user about job done and their part is getting delivered or can picked up. User can rate the part and other parameters of that delivered product and services. After that, the payment will release automatically through payment [login to view URL] that service provider. We will use payment gateway having all kind of payment facility like other eCommerce companies are using. Portal should have advertisement space. Product selling space in a front page. Image display facility like that. For reference you can visit [login to view URL] to get an idea. Almost all that task would be like this website (appox 80%) and many thing would be an add on features.
