Hi Kumar! I could help you with the T-shirt printing format. I have 3 years of experience in graphic design. Previously, I used photoshop (Psd) to design several t-shirts for school association. Each design might take around 3-5 hours. If you have many designs to work on, I'll try my best to complete within 3-4 days. As for the printing format, a psd file can be used to complete this job. Thank you for reviewing my proposal. If you want, I could get to work immediately to suit your due date.
Regards,
Mohd Danial
