If you have any suggestions or want to benefit from royalties for ur design?

I have a plan for the design of the shirt, and I take the cultures of my country in the design. i plan to offer the company designs and obtain payment for the design itself (the first payment), and royalty and percentage of revenue from selling shirts with my designs do u have any suggestions or forums that can help me to start that? thanks

I would like speak with an attorney to make sure my rights were covered before we go any further!
