Just answer questions from people who have specific questions. Over the years I've learned it's easier that way. I've seen too many people try the "I'm going to create a thread where people can ask me for advice" and who either ignore questions or the information was lost due to the length of the thread.
If you want to solicit your services as a professional MUA be prepared for people to ask for credentials. Anyone can claim to be a professional MUA but very few are and not having those credentials separates real pros from those calling themselves a pro.
