Adobe Photoshop retouch

Hello - I have a job to retouch and resize about 50 photos for a new website. They are headshots of people. The instructions are below. Would you be interested, and how much would you suggest as a cost per headshot. We would give you high resolution photos. We need this right away. The photos need to be: 124px wide X 138px high Each photo needs to be cut out and put on top of a grey background. No shadows. Their heads need to be close to the same size. They should all be created from photos that are larger or the same size as the final size image. No blurry, pixilated photos. The final file format must be a web optimized jpeg. Grey color: R – 226 G – 226 B – 226 I already attach a sample . please come up with portfolio & best offer.
