Greetings Sr,
You can check me profile to know more about my skills and experience.
Proposal:
A website for you budget, I recommend use of CMS with e-commerce plugin integrated.
I will use Joomla Virtuemart to develop your Online Store.
I have enough experience in developing stores with Joomla / Virtuemart , you can look at my portfolio and see an examples of online stores.
Your Online Store will have the following features:
1 - Registration for users requesting user data like name, address, etc ... (the fields are customizable according to the needs of your business) .
2 - In the main page can be placed Images SlideShow , its outstanding , recent product promotions to advertise them without the client navigate around the site for them.
3 - Option coupons ( given the user enter a code )
4 - Multiple categories of buyers. (basic, premium , wholesalers ) . This is to offer different prices if required .
5 - Integrate payment option for the end customer , you can choose (eg paypal , etc.) or simply sends an e-mail with information to perform a deposit or bank transfer as required .
6 - You can enable or disable the online shopping easy by allowing products continue to show but preventing the purchase , leaving as a catalog .
7 - Choice of multiple payment currencies (EUR, USD , etc ...)
I will teach you how to edit the content and manage products in the backend.
We can discuss more details in chat.
