Hi, Matty and welcome to Modelfolios!
Are you looking for an agent or just to model on your own for right now? If you are looking for an agent, simply Google modeling agencies in your area and visit their websites to see what photos they want and if they have any open casting calls. At minimum you should have the following to show:
- Headshot (one smiling and one not smiling)
- Full body shot (in shorts and a well fitting tank top with no shoes)
- Full body profile (both sides, the same outfit as above)
Because you're a new model you don't need a resume or cover letter since you are just starting out. The three images listed above are all you need to get started. You can also continue doing test shoots with various photographers. Make sure the pictures reflect not the type of modeling you "want" to do but the type of modeling you meet the requirements for. Being realistic about the types of modeling you can do will make you more marketable to agencies and potential clients.
Feel free to let me know if you have any other questions or concerns and I'd be more than happy to help you out.
