Any idea if I can get some paid/pro bono help with my app?

I have designed almost 90% of my app but sometimes tend to get stuck with niggling problems that take a lot of time to resolve.
Are there some folks here who can provide pro bono (free) help?
In fact, if the resolution is time-consuming I don't mind compensating with a bit of cash.

For the free help, just post the problem you are having and your relevant blocks.

Thank you.
