Interspire Shopping Cart Developer Needed - repost 2

Hello, We have a Interspire site that needs some extensive custom programming. We require strong English skills to be able to understand our logic and need of programming. The main task will be to make our checkout process identical to simpleachievements.com. We have different levels of products which require different processing times. Using these times, we need to develop a way to show the customer an expected delivery date based on the products in their cart, the type of rush processing (if selected) and also the shipping method. We are also needing bulk pricing applied to multiple items of the same type. Prior to being hired, you will be put in touch with a representative of the company and will communicate in depth about what is required and the status of the job. Again, we will only hire if you have great English communication and Interspire skills (someone in the USA is preferred). And if you can communicate by telephone, that is a PLUS! Once again, we require direct communication prior to hire so that you completely understand the projects requirements.
