First of all, you should do a proper online research about different acting agencies that have a proven track record of helping people in finding acting jobs with leading names in the industry.
Write down the names of a few established acting agencies and their contact details including phone numbers, email and postal addresses.
Always give priority to famous acting agencies because an established agency always hires talented people and chances are high that you will find a reliable and credible acting agent who will lead you to the threshold of acting industry.
After selecting a few acting agencies, try to send them your credentials including your qualification, pictures, weight, height, hair colour etc, via email.
Do not forget to make a phone call after a couple of days to these acting agencies in order to verify whether your application got their attention. Most probably you will be contacted in one or two days or, in some cases, at the same day.
Do not forget to participate in college or university theatre shows and also in your community shows which will help you to grab the attention of many acting agents representing different acting agencies.
After getting appointment with one or more acting agents, you need to prepare well because they can ask you for a live demonstration of acting. It is your chance to make a strong impression on the acting agent which can earn you what you want.
Try your best to become polite in your conversation during your meeting which will also create a positive impact and chances are strong that you will get accepted by the acting agency.
