Thanks for your advice! Are you working solo, or for a studio?
Most professional studios are happy to spend $299 for a tool like CrazyBump. It helps artists work more quickly, and that saves a lot of money.
As a quick calculation, consider the value of an artist's salary, benefits and office space. Then figure how much time CrazyBump would save over the length of a project. Then multiply. For most studios, the product is in the thousands, so they see CrazyBump as a good investment.
If your studio director is unconvinced, try showing her the "fast materials with crazybump" video, at http://crazybump.com/video
OTOH, if you're working solo on an independent (ie non-publisher-funded) project, please drop me an email. Indie licenses are available on a case-by-case basis for such projects!
