can you give an example of how realistic and playful ?

Sure. If you visit the link to the Franklin Institute website http://www.fi.edu/dinosaurs/ , their logo is about the right level of both. It's realistic but has colors that are a little bit more fun.

ok but thats very detailed "art work" its not in the same class as a logo design, can you incress the buget and guarantee the conest ?

id love the take part but i cant spend that amount of time on a none guaranteed project and at 200$ it would have to be atleast 400$

if you can then feel free to re-invite me,
Many thanks
Inspial.

Hi,

Thanks for the invite.

By playful, do you mean a cute looking dino reastically rendered or a real dinosaur with just playful colors?

Hi
I visit the site.
Your concept is really great, but i wanna know do you need iconic and in some way reductioned sign
or just cluttered logo with many dino's hanging around text...
Thx

Hello,

If you want me to put a little more detail into the dinosaur that I made (unlike some of the copyrighted images I see others have done :P ) let me know...

My design was: http://www.designcrowd.com/design/614929/logo-design-by-white

P.S. I could probably even make the full body if you want, like in the example you gave us...

Cheers,

Simon
