Improve my logo for printing

I have a very basic logo I designed myself that I use for my basketball clothing and coaching brand and I need someone to sharpen the logo or possibly redesign it (not essential as I’m happy with current simple design) and create numerous files for use on Printful etc to have printed onto clothing.
Logo will need to be sent in numerous colours approximately 6 and size of images and formats best for uploading to the 3rd party site and then printed onto the clothing or merchandise.
