39DA/48PA - where should isell backlinks/blogposts?

Hi everybody,
So i have a 39 DA / 48 PA WordPress themes related website, around 50 unique content wp themes related pages.

I'm looking for a way to monetize it by selling backlinks or guest posts , what would be the best way to do that?
I'm currently thinking of using backlinks.com to sell some homepage links.

Thanks!

you are a newbie so you can't sale in BHW. So try fiverr.
