Modify a logo in Adobe Illustrator / quick money

I have a logo IBF which is for a gold trading company. I would like the logo to be slightly modified (in vector format) so that it has some "3D effect". So this is just about fine tuning the existing IBF logo and extruding it or putting some light reflections or gradient etc. on the existing vector shape to make it look more sexy. This is a small piece of work but I have more work in the future if this goes well. To bid for this project ideally provide a watermarked version of the proposed design or show samples of other design work of a similar nature.
