Hi
My name is Tom Moser, I'm a professional pin-up artist from Melbourne Australia and I'd be very happy to work with you on the ironworker t-shirt design. I don't believe that written applications for art-based work make much sense, so I'll attach a basic, conceptual sketch for the design in the following message (freelancer.com somehow doesn't allow to attach anything here).
Also, you can check my profile and portfolio to judge my skills.
Regards, Tom Moser
