142224 foam quotation system

I want a foam quotation system designed like this [login to view URL] The system must integrate with a shopping cart to allow people to get a quote, and then buy the item at the price quoted. Not to fussy on what shopping cart software is used as long as it is fairly SEO friendly, so probably zen cart or the likes might be best. I am however open to suggestions. You are going to need to ask some questions I would say, so please ask away on the PMB. Any question other than 'what is the budget' will be answered. I will not answer 'what is the budget' because if you know the work involved YOU should know the cost involved. Once the quotes are in, I will talk to those who make the most sense. I am not looking for the lowest price at all costs, I am looking at the best person for the job, including communication and understanding as well as initial gut feeling from the PMB & Quote.
