Architectural image editing -- I can do that, and do it well !!!
As an architectural/real estate photographer myself, I understand exactly what you need and how to achieve it. I actually prefer the post production role, so I'm happy to let you shoot while I make the images look great.
My bid is for my hourly rate of $50/hr. I work quickly, thanks to my experience and the collection of my own custom-built Lightroom presets and Photoshop actions I've created to do this kind of work efficiently. A set of 15 images like your sample would take less than an hour. Exteriors and interiors without windows can be done quicker. We will need to discuss your ratio of windows/no-windows to come up with an average for a base price per batch.
I can also do sky replacement, small object removal, virtual twilight, etc., if you want.
