Image Tweaks & Replication

I need a graphic designer to produce/copy and modify 20 images for me. I will provide base images/links to them, which already exist but I need them transformed with some tweaks to avoid any copyright issue like adjusting fonts, placement etc. I need each image in photoshot format, A3 size, 300dpi, CMYK format. This is not a one time job as after first 20, there could be more but that will come later. I want to start with 5 images to be done first, then once they are ok, we move to the next 5 and so on to complete 20. To filter out automated responses, please write answer to '5 + 5' when starting your reply and I will read all replies where someone reads the full brief and provides an answer. Any questions, please feel free to ask. Thank you!
