Sorex and I started a conversation in private, where I explained him about my project, and I think all misunderstandings are sorted out by now

I understand his concerns. For sake of other developers that might be considering answering in here, Let me openly answer his concerns:
1) I am already swamped between family (including two kids) and the summer vacations that just started down here. In top of that I got to take care of mantaining what actually brings money into my home (got some websites and apps monetized that need daily maintenance) So I do not have any real coding time left to start this coding project.
2) it is my personal Aim, my own "monetization pet project" in order to "revive" and/or refurbish some old (flash based , arghh!) game apps I published on Play Store back on early 2012. I need to get rid of those flash games, which I left them forgotten for just too long. My aim is to replace them with some very simple, yet nice playable games, in order to start monetizing them.
I am considering a six months window in order to complete this project, which includes several steps (the coder will surely start delivering the first basic4android projects right from the first month).
3) I am a developer myself, so if you are serious, you will not have any communication problem with me: I would expect an orderly work and I would pay on a monthly or by delivered results basis, I am flexible about it.
I would also be able to understand any unforeseen situation and help the coder to find solutions or alternatives. The delivered games and source-code will be "mine" for my exclusive modification, publishing and monetization. The coder will be able to place his name and get credit for his or her work, inside each app.
