Brainstorm brand/tshirt ideas

I need someone to brainstorm ideas for tshirts slogans and ideas for illustrations. I own the website vetbizpages.com Which is a directory of Veteran owned businesses. So I need slogans to match the theme of the website so an example slogan would be "Support veteran owned businesses" I would like at least 10 slogans. If you have an idea for a illustration to go along with the slogan that would be great. The website is https://vetbizpages.com/ If you can supply 1 sample with your bid that would be nice. Thanks
