logo design - vector graphic pt.ii

need VECTOR GRAPHIC produced for an upscale housing community (called "Lakeside"), to be used on their roadside sign and in their marketing materials. they'd like the logo to include: a lake, ducks or some sort of water bird, cattails. i'm looking for smooth, crisp and clean graphic, somewhat more suggestive in concept rather than realistic depiction. the client really likes the concept attached ([login to view URL]), but I’m incapable of producing vector art, and I’d like to get the birds, the cattails, etc. just a little more lifelike in shape. feel free to go ahead a mock up a sample, or redraw what i've done, only cleaner, crisper, etc. Otherwise, please include with your bid a sample of similar work history. ATTACHED: 1 - a sample graphic concept to jog some ideas. 2 - pics of similar roadside signs
