549328 Photoshop - use thumbnail photo to create larger image

I have a photo headshot but it is 150-250... the detail is good but of course it cannot be blown up without distortion and pixelation. I need someone to take that photo and use it to make a larger version with full body. It must be realistic and look like the same person. Provide examples if you can... if you read the project and understand what needs to be done send me a PMB and say "I understand and am able to do this" and provide examples if you can. Thanks! Ps. UNDERSTAND YOU WILL NOT BE PAID IF YOUR WORK LOOKS FAKE LOOKS PHOTOSHOPPED OR IS PIXELATED AND GARBLED. IT MUST LOOK REAL AND BE GOOD QUALITY!
