Image editing before / after pics

Can you help ? I am a gardener/landscaper and take before and after photos of my work. Sometimes the images don't match each other that well - slightly different angles, sun on one side then the other etc. I'd like to have the images edited to make them line up with each other, make fences look vertical (important when I've built a new fence !), lighten up shadows etc. Often the images are taken on a phone so not always the best quality.
The example photos are typical, in this case the backgrounds need lining up with each other and for the after pic the last fence panel needs darkening up to match the other panels, and the fence posts need to be made to look vertical. (It is straight as a die in reality, honest !)
Please let me know if you'd be interested in this work. There should be some repeat work for you if it works out well.
