Online Logo Designs

We want to get real like logo design. Want to feel our existing logo like it really is there for grab. I have found some websites n send inquiries but want to know about what others on the web know (better ones). Thank you.
Quality must be like:

OR at least

Please I don’t want to blindly run a design contest. I want to past work of 3d designer (3d logo designers).

http://www.3ddatalabs.com sample logos are very good but too expensive.
correction: We want to see previous work of logo designers.
