looking for a walking dinosaur . Is there anyone that could make me one

There are a few companies out of China that are selling them right now.  Here is one:  http://onlydinosaurs.com/features/walking-dinosaur-costume/

I'm not sure what their price point is, so you'd have to reach out to them for a quote.  Likely in the $3,000-$5,000 range. 

http://www.jurassiccostumes.com/ is another source.  Some of their stuff in the past has been quoted at around $5,000. 

And you can find a product listing here as well:

With any of these manufacturers you may be able to talk the down on price a bit.

Best of luck!
