Retouching Photos

I rent homes across the UK and take photos that I require to be photoshoped to bring them to their best. I would ideally like to give the correct person a set of 10-15 photos and have them all retouched. i.e. Lightening, straightening etc.
An example of the type of photos you would be working with can be seen at https://www.dropbox.com/sh/l0ze0m6setx26h5/H54-5929nt an example of the type of photoshoping can be seen at http://www.discoveryholidayhomes.com/view/Seaduction.aspx
I would like a fixed price per batch and this would be regular work.
