Shopping Cart System to Integrate with Website Layout

Avg Bid (AUD)
Project Budget (AUD)
$30 - $250

Project Description:
I have a website for a client which is already completely designed. The client doesn't want the design to be changed whatsoever other than the product pages which should look roughly the same but be a integrated ecommerce system.
The system that is currently in place does work but is through Paypal and does not allow the client (who has no knowledge of coding) to change sizing if one side runs out (which usually go disabled in online stores when sold out), doesn't have a general sold out system, doesn't have a check out or shopping cart which is integrated within the website, and does not allow for the number of items to be shown or the calculated price of the shopping cart.

I would like to work with someone who has a stylistic design sense and can work to exact specifications.
Basically I need the system to include the following:
- Be able to have a calculated total number of items in shopping cart
- Be able to have a calculated total price of items in shopping cart
- Preferably produce dynamic pages for items the same as the current website
- Have a shopping cart and hopefully a checkout which is integrated within the website design
- Allow paypal payments
- Allow a sold out system
- Be able to have choice over colour and size of the product
- Allow for changes to items/quantity of items etc
- Hopefully a CMS for the updating, adding and subtracting of products for the client (who has no previous code knowledge).

I am happy to choose a good price for the project depending on quality and experience in the area. I'd like to see some examples of the persons work in a similar way if possible.
