You have already gotten excellent tips and leads but continue to ask for information handouts. Most of us spend a considerable amount of time searching, researching and procuring assignments. Personally, I am offended that you've come here to ask for quick and easy directions straight to your goal and have not mentioned any routes you have already taken on your own to reach that goal. Moreover, anyone who does editing, enjoys it and makes a living probably would not give you much information, as well they shouldn't, because you would then become competion for them in obtaining those gigs. My 2 cents, that's all.
Please remember to respond in your postings in a way that is helpful, thoughtful and kind. It is not uncommon for new Forum members to ask questions about which MSC shops which Client. When this happens, please refrain from name calling, and please respond without making any new Forum member feel unwelcome. Thank you.
