This forum is for help and is unique from all others I have used, in that the amount of comments posted that are unhelpful. If somebody asks for a hint then give them a hint, it's that simple. but most on here are noobs asking for help.
You need to remember that the pay here isn't all that great. We're all volunteers. Sometimes that works; sometimes it doesn't.
If the project is important to you, and is beyond your skill set, you have two choices. Expand your skill set (learn!) or head over to Gigs and Collaboration, and offer to pay for the help you need.
I've got a few "how to" videos on youtube machining related, but I'm not asking a payment for them, just done it to help others. This is what makes the internet great, expanding people's minds.
