Best online site to advertise and sell hair

I'm planning on selling 20 inches of my black, Asian, virgin, straight hair (thickness is about 4 inches) but I need to know reliable sites for that and what exactly is the process is like if anyone knows.

I tried logging in the worth of my hair in SellOn.com and it cost about ~$300 don't know if that's USD though, but i live in Canada, BC for reference.

Thank you so much to whoever can help me!
