Hello. I would love to help and have a lot of experience in logistic & sourcing. My primary job is logistic manager so I see these type of invoices daily. Although most are from EU . Some of my previous work you can see in my profile.

I propose that I do a research of companies that can provide athletic wear with the logo, in USA. I would do research, make inquires about prices, MOQ and shipping rates. I would need some additional info (where to ship, type of fabric, colors, quantity, etc ..). But it can be done. We just need to set a number of how many you expect. Message me with any question, happy to answer always.
All best.
