4 x tshirt designs for childrens slogan tees

I am looking to produce some very simple tshirts for kids which have four slogans across them . I need to have the designs in a format that i can send across to the printing company

The slogans are;
Crawl, Walk, Yoga
To do list: Nothing
Non stop fun
Ethicool

I am looking for someone that can design some fab but simple tshirts that i can then get printed.
Once we've worked out which font looks the best, then the same font/style will be used across each slogan tee
I need this done within 2 days if possible
