hey guys, im not sure if this is the right section for this but i want to make a website that requires more coding knowledge then i have. ( i only took a few classes on HTML in high school, learned a little CSS on my own and currently taking JAVA in college.)
i want to create a site that allows users to search for a certain item using a drop down menu ( like searching for a car on ebay) (make, model, year) and then sent to a page with information regarding the item selected.

i also want a classifieds section, separate from the information section. like a Craigslist but only a few categories.

i have limited knowledge like i said so any input as far as how to go about doing this would be great
if someone could point me in the right direction for this it would be very helpful
