Selling: I have been selling on here for quite a few years. I have gotten to meet a lot of cool clients from around the country helping them with motivation, marketing, studying, and beyond. It's been an awesome platform to beta test business ideas.
Buying: You can hire people for all kinds of cool things. I hired two teenagers to make a rock video for my friends B-day! I hired a guy in south America to do admin work for me for one of my clients and it was a huge help.
I have also been a speaker for them before too!
