Best Way to Organise Buy, Swap, Sell, Classifieds Functionality/Page

Hello! 🙂

Are you able to advise me what’s the best way for me to go about setting up a Classifieds/Buy & Sell kind of page?

My website, Diving Buddies, is a community scuba diving network. I want members to be able to post their equipment for sale, or search for other members’ stuff to buy.

I was thinking I could use your Stylish Woocommerce theme demo as the page, (http://seventhqueen.com/themes/kleo/stylish-woocommerce/) where it has the search functionality – but how would I be able to configure that so it only searches for products for sale or products people are after? Is this where members need to make sure they tag it a special way , or is this something i can preterdetermine?

I think the best way would be to create a special  Buy, Swap & Sell Forum, where people can post their topics/replies of interest…. but I did wonder how I could attribute those to be included in the search results on the Stylish Woocommerce page?

Alternatively, is there a section I could add onto the members own Profile page where it can put what stuff they have for sale?

What’s the best way to create a Classifieds section? Would love to have your opinion 🙂

Thank you for helping me as always,

Tahnee

P.S. I’m getting closer to finishing the website , kind of 😀
