If there is a specific bug you are trying to report, then https://tracker.moodle.org is the place to post it.
If you need a developer to support you directly, then you could contact a Moodle Partner at https://moodle.com and they should be able to give you a quote for that support.
Other than that, most of the people posting on the forums are community volunteers - if no one on the forum happens to know the answer to your question (particularly on lower-traffic forums like this one), then it is likely that you won't get an answer.
