Custom T Shirt Design

I need a custom t-shirt design for our business (Tritan Autoworks) a car repair business in Lagos Nigeria. we need a design that is modern and friendly. The shirts are going to be worn by all staff we want people to see us and engage us whenever a member of staff is seen wearing the shirt. The use of our company logo is not compulsory as we don't want to limit design ideas or creativity. Our website is currently undergoing maintenance so you can visit our Facebook and Instagram handles for more information on the business. https://www.instagram.com/tritan.autoworks/?hl=en https://web.facebook.com/TritanAutoworks
