Searching for wigs

I have been looking online to see if I can find anymore wigs as well as looking in the shops to find all the possibilities for my characters.
Unfortunately my budget isn't huge which would be a restriction  It is very hard to get wigs which will look good under the camera without looking too synthetic as this could be a problem when shooting.

The wigs below would be for the Kalidah, the orange and the black could work well with the makeup.

The wigs below are for the tin man, a silver wig would be ideal as I plan to spray all of the tinman in silver.

The wig below is an idea for the china clown, the short wig would look very editorial and modernize the clown.
