I do not offer support via email. For support with Advanced Forum, Advanced Profile, and Author Pane, use the issue queues so everyone can benefit from the answer. If you have questions on an article I have written, you can leave a comment and I will try to help if I can. For general support questions please use the drupal.org forums. If you email me for support anyway, more than likely I will ignore your email. I hate being rude but answering even a quick question often ends up going down a rabbit hole of continued support.
I am not doing any freelancing at this time. I am keeping Drupal a hobby until my kids are old enough that I can devote enough time to freelancing to make it worthwhile. If you are looking to sponsor a feature for one of my modules, I may be interested in that. If it's something I'm going to be doing eventually, anyway, I don't mind getting paid to bump it up in the queue. :)
