Place a logo and text on a shirt image - male and female

I have two images, one male one female, wearing a white polo shirt. I need someone to put a logo on the shirt and also some text. A provider on here already did this once for me but I need to post this project incase she doesnt get back to me. This is an urgent requirement. $40 on offer for the job. MUST look professional and not just pasted on. You will also need to source some flags to place as well - easy enough. Quick job for someone profficient in photoshop. I require the hi res image back AND all source files you create (PSDs etc etc)
