We love helping other users and we love Joomla! Any work we do for Joomla! London is not paid by or endorsed or associated with Joomla! If you want free help, the above sources will offer you either a premade answer or faster and more help than we can offer you. They are manned by more people with a diverse skill set and knowledge base. Plus, any question that is answered is there for other users to find, which really helps the Joomla! community. If you're still stuck, we encourage you to bring your problem to a meeting and we'll try to help you. If you really don't have time to do any of those things or you'd rather just pay an expert, feel free to reach out.
