Hello there! I see that you're looking for an illustrator with experience in anime style who can turn your son's photo to anime, and I believe I would fit perfectly in this project since I mainly draw in anime style.
I would also start with a free sketch of your son's face (before you pay anything).
Please, check my profile and reviews here:

And contact me for more anime samples!
Looking forward to working with you,
Best,
Jumana
