Easy Mockup and color change in photoshop.

Hello,
I have 710 design file and color code, you just have to drag the file and change color code in photoshop and drop it on the mockup of t-shirt and sweatshirt. And have a good eyes for adjust the design size and position on the mockup and export it good quality png file format. Basically you have to make each t-shirt and sweatshirt 14/15 color. If its wrong color and wrong position then I will need revision as well. Let me know how long does it takes for complete.
*You are not allow to use the design anywhere and share and you have to sign a document for this.

Thank you.
