Hi, as you said that you are new in copywriting then first I would like to suggest that you should get involved in forums. Its very place to discussion about all things related freelance copywriting. After that you can visit www.lifeonavenuez.com where you can follow the antics of a new freelance writer as she starts her own business. It is really a good resource for new freelance copywriters. Hope my advice would help you.
Good luck!
