I think the reason you're being met with such resistance, is because it's a tradition here at scirra that dates back to the...
ok, no, but seriously, this is about the 2,000th "please help me make my game" post. There's nothing wrong with that in and of itself, but over time there has developed an unofficial, but fairly consistent, and generally agreed upon set of standards by which the people who've been here believe a potential collaboration should be evaluated. Reading through the posts, I can see how it probably seems everyone's jumping down your throat. Basically though, I think what everyone's trying to say is that anyone skilled enough to help you, can get to the point you've gotten by themselves in a fairly short amount of time, but with a game completely tailored to their tastes in every way, with their own terms as far as how much money they might want to make, and a level of absolute control over the project.
So what you're offering is to take away full control, take away the possibility of financial gain, to help you create Your vision. It will probably be a tough sell, but nothing to feel like an evil overlord about. And don't hesitate to ask in Help/Tech Support, some of the dead ends that made you turn to asking someone else to do it for you might not be as bad as they seem. Asking in the forums for advice on how to make an inventory/combining system would probably yield better results than chat, there are plenty of people here on the level to help you, and although I consider myself fairly skilled with construct, sometimes the simplicity of other peoples' solutions surprises me. So basically, as hard as it seems to get up to speed in Construct, it'll probably be easier than finding a lead coder or tutor. If you showed a storyline written by orson scott card, and artwork by hr giger, I'd probably hop on, but in the meantime it's your baby, and most people are already busy with their own.
good luck though
