Find out how the business actualy functions and how you fit in to it .
Learn what the product you are selling/marketing is first.
Without direction or focus in the work you are selling (that is the product , your services) there isnt a platform to begin writing a business plan on.
Then get off of Modelmayhem and go out in to the real world..
This isn't the industry and asking how to find work on a website where 95% of the members are either asking the same thing or don't really care .
Get on Google start looking for books , search sites of the pros who are actualy working and ask about assisting , looking your area(London is a MAJOR hub) and start there .
Make a serious effort BUT make it in the real world .
Not on MM
Best advice I can think of giving you or anyone else .
