Crear una página web

I need a new website. I need you to design and build a website for my small business. I'm looking to have a website designed and built as soon aa possible that has the ability to act like a comparison site for product. The searching base will be a given set of vendors which will need to be easily amended at anytime in order to add new vendors. I have a domain name ready. The website will need to have a search facility that when the customer enters the name of the product it will search all of the including vendors to produce a search result of all of the vendors that stock the item. This will be for a set industry which will be explained to the right person. There will need to be a page for vendors to fill in a membership request form that will email the request. This needs to be implemented as soon as possible. I don't have a budget in mind but it needs to be as cost effective as possible as I am trying to keep startup cost's to a minimum. It is my understanding that above could be implemented withing WordPress with an API plugin but you tell me. Software licensing is my area not web design.
