Welcome to the Wannabee forum!
You will find plenty of advice here from people with varying degrees of experience - all willing to help.
However you will find that most of your questions will have already been asked and answered many times already ( and some quite recently!).
May I ask you to spend a little time researching the forum which will not only produce the answers you want but will teach you more about the industry as a whole. You may find the Search function helps.
Good luck
