Football Kits
If you'd like to have a football kit made up for your amateur football team then you'll find that there are plenty of businesses capable of producing the shirts, shorts and socks for your kit. Many of these companies advertise their services online and they will be able to produce a kit in your colours embroidered with your insignia. Many of the firms that produce clothing and promotional gifts for companies to use for advertising purposes are able to produce printed and embroidered clothing, so it may be worth contacting one of these companies to see how much they would charge. Although they would typical embroider promotional gifts they have the equipment available, so some would be happy to produce football kits too.
Because having a full kit made up for every member of the team is pretty expensive it is company practice to have a company pay for them. In return they would expect the kits to bear their name and branding too. Many businesses will sponsor their local amateur and youth sports teams. If you don't think that your team will be able to afford to have kits produced then it is probably worth getting in touch with some local companies and see whether or not they'd be willing sponsor the kits for you.
Having your own kit makes a lot of difference to the team and the players will feel more confident on the field, playing in their own colours.
