Hello

i was surfing on Unity Assets Store and i found this one:

https://www.assetstore.unity3d.com/en/#!/content/19982

and i liked them so much,

do you know any place sell similar to these ? (i dont need animations)

or any Artist who can make like them?

That style of art is called bobble head, chibi, or SD (super deformed). So you can try searching for those terms.
