i have several pfojects on my google play account, but i dont have resources to promote them, so i'd like to sell them for my further projects

you can ask if u r interested in them

here u can take a look and name your price https://play.google.com/store/apps/developer?id=GSG-Games​

or maybe you know where i can sell the whole project with sources

Why don't you try steam ? or create your own website with a market ?
