LOOKING FOR TSHIRT EXTROIDANAIRE

I have my own brand. I have three logos already created but probably could use a little touch up. I need a ton of different designs for men and women to start. I need about 10 designs for men and 10 designs for women and about 10 unisex designs. I have the logos and the wordings that I want used. I just need someone to design all of them and put their own flare to it, but I need something very unique and lasting. Not something in today and out tomorrow. My brand will be Faith Based Activewear, T-shirts and such - but I am starting out with the T-shirts. What is your best price for what I described?
