sorry if this is in the wrong category,

i want have a search engine, say if you type in 'ipad' it will bring up an 'ipad' from all the websites that sell an ipad, along with the price next to it, and round it up to 10 ipads arranging them in terms of price, from lowest to highest.

please somebody help me find a search engine that i can put into my website.

ive already brought a domain, and im thinking of using squarespace, any other suggestions to squarespace?

thanks.

ps. im no programming genuis.
