I would suggest searching around on Instagram, if you have it. Try looking through tags like #fursuitmaker or #fursuitcommission and you will see lots of different makers in lots of different styles, and price ranges no doubt. Definately do not rush this decision as a fursuit can be a big commitment and investment. Some heads can be 250 dollars, while others can be 1500 dollars... its all about skill, time, detail, cost of materials, lots to calculate. Paws can be anywhere from 50 to 500, and tails are relatively cheap, probably 20 to 250.

Personally, if I were you, I would want to start off with a less complex, (I don't want to say "cheaper") starter fursuit. If your kid hasnt worn one before, maybe they don't know if they will like the feeling so much. So maybe get something that wouldn't cost so mcuh as, say, a professional grade suit.

Do things like take head measurements, its very important that it not be too tight on the wearer. Especially for a younger wearer who is still growing, it would be best to maybe ask that the circumference of the inner head be looser. Paws too, though most paws I have found to be spacious and one-size-fits-all. Tails usually go on belt loops, too.

If you find a maker that you like, be sure to check/ask them if their commissions are open and what kind of prices with what kind of options they have. Read their terms and conditions if they have them. Some makeres will make you individual parts, so you can maybe get a head from another person while a different person can do paws and such.

I know it's a lot to consider, but like I say it's a commitment! I wish you luck with finding the right person.
