Really need help using Acquisition.

I followed this tutorial on youtube : https://www.youtube.com/watch?v=HeqU9jkWRy0
But i have no idea if my items are actually up on Poe.trade and no one has contacted me to buy things even if i set them at really low prices.
My stash is completely full with items that i can sell but i have no way to sell them.
If anyone could help me i would really appreciate it.
And please dont bother if your answer is going to be " Just buy premium stash tabs".
