Designer,art & ai photographs

Hello! I am looking for a skilled designer to help create high-quality art and AI photographs for my project. The type of design work I need is logo design and I have specific ideas to build on. I am also open to the designer's creative input as needed. I am not sure, however, what types of formats and sizes of the logo I need and am therefore requesting advice from the designer. I look forward to hearing from creative professionals to make this project a success!
