Need a Logo and Biz Card for Design Biz

I have started my own business in structural and architectural design and drafting using AutoCad, specializing in roof design - and I need a cool logo for td designs.

td designs

Tagline: cad drafting and design services Desired Style: Simple, but I am open Accepted File Formats: Standard Web Formats (.jpg, .gif or .png); Vector Formats (.eps, .pdf or .ai); Layered Formats (.psd or .tiff) I am looking for a logo for my new company - td designs.  I do structural and architectural design and drafting work using AutoCad, and specializing in roof design.  This logo will be used on each drawing that I do and will be placed in the Title Block, and I would like to have a business card designed that will also show this logo. On the business card somewhere I would like it to say - CAD Drafting and Design Services, along with my name, number, and email. One thing I like is opposing colors on biz cards, like where TD would be in a shade of green and the background would be in white, then the other half of the card would be in green and Designs would be in white, or something like that.  But I don't want all of your designs to show that - I want to see your own creations too please.  I am pretty open at this point, but I would like it to be pretty simple.  I also like the idea of all lower case letters, but again I want to see a variety of designs.  This logo will also be used on a letterhead at some point.  Please show me what you got.  Thanks!

Every design category has flexible pricing for all budgets. Logo design starts at $399.
