coloring and correcting some Hieronymus Wierix engravings which I have as jpg images [Urgent]

I have 19 Hieronymus Wierix engravings in jpg format that need to be colored and corrected. I will provide the images through WeTransfer or you can also find them on rawpixel.com. The initial color pass can be done with AI, but I expect 30 minutes of hand touch-up per engraving to ensure a professional, non-AI final look. An example colored with AI will be provided to guide the color scheme, such as rose-colored clothes for the child Jesus, light blue for the angels, and more vibrant colors for backgrounds and clouds. Corrections are needed where AI may have introduced incorrect details, like unwanted elements, and the full scene should have consistent color and finishing. The goal is a more polished, hand-crafted appearance. The project needs to be completed before the end of the month.

Budget range:
$250 – $750 USD

Examples:
There are 19 engravings I want done. I can send the jpg’s to you through wetransfer. They are also on rawpixel.com

I estimate that the hand touch up after the AI should take about 30 minutes per picture, so I would presume for the 20 pictures it would be 10 hours of work…

I gave one example that I colored using AI, which is meant only to give you an idea of the color scheme. Rose colored clothes for the child Jesus. light blue for the angels. the AI added snakes under the heart for some reason, that obviously is not correct. Also the full engraving should have color to it, even the ground between the reptiles, and it could be touched up quite a bit to give a more professional hand done look… The cloud colors could be less black and white toned as well… for example…
