In as much as I appreciate your sincerity but I think you should be taking a more aggressive approach if you have positioned yourself to be ready for it. Although, I am yet to see that because as a prospective bounty manager, if you are not limiting your options to local boards, then your command of English should be solid which is not convincing enough based on what you wrote.
When you have settled that, take initiative rather than asking, create ANN Thread, move on to assisting with bounty calculations, spreadsheet update, tweets counting, focus on projects coming out fresh, sell yourself to developers and be dedicated to it. Put all of this together, you might get the chance to your dream contribution to the forum.
