MySQL. It's free and it's a relational database. Then add your PHP-code to do the work.

Hello,
I am starting a new business online which will generate income through ads. I need to make a database that will contain less than 1000 listings that are searchable by less than 5 criteria. Just starting up, I am not in a position to pay someone to make this (but would love to!). I'm looking for software that can get me started. I've heard these are not easy to make, but is there a package out there that is easier than others? Something that does a bit more handholding than others with less assumed knowledge?
Any advice or suggestions you have are most welcome!
