Retouch a folder of photos to be used on social media

I am looking for a graphic designer who has the photoshop tools and skills to retouch photos in various way to make them more visually appealing and suitable for use on social media. Some photos would be a simple colour retouch, others cutting and others removing background so that they can be made into banners.
Please send examples of what you have done previously

There are total of 40 photos to start with but there will be more if we are happy with the work.
