Sponsorship proposal for my biodegradable apparel launch

I am looking for a sponsorship proposal to launch my new biodegradable apparel brand. From funding to advertising and everything in between, I need help to get this project off the ground. My target audience is adults aged 18-25. A sponsorship proposal of 2-3 pages should succinctly capture all the details that are necessary to start the launch process. With your help, I am confident that my apparel brand will be a success in the marketplace.
