Design Apparel mocks for a Kickstarter

We are launching a kickstarter and need some mock up images of apparel (look as realistic as possible) we'll offer for the fund raising project. we are doing 1 T Shirt, 1 hoodie, and 1 hat each image of apparel will have a background of a big wave or theme of surf. I have image example. I have PSD templates for TShirt and Hoodie or if you have a better one..great. I have a hat jpeg image but hopefully you will have a better one. I have T Shirt logo just needs to be combined with T Shirt template and designed. I have the Logo for hoodie just needs to be combined and designed Hat design is were im stuck at and will needs some options by using the logos supplied Final Files will be one of each piece of apparel separate and a image with all 3 pieces of apparel together because we will have an option for a bundle.
