Business Logo Design

We need a new logo for an existing company. My client has already put together several rough sketches/ideas for a starting point, but needs a professional graphic designer to add some creativity and polish. Ideally, we'd like several different ideas to choose from. I will forward the client's rough ideas to the winning bidder. Here are the technical requirements: --> Finished logo should be at least 1200px wide with a **transparent background** (important!). --> Height is flexible. --> 1200 points/inch resolution --> CMYK color from start to finish. --> Should be delivered as a vector file, with any layers intact. --> All copyrights will belong to my client. This client is very particular with details and so you should expect to make several revisions of a chosen design. Please take this into account when formulating your bid. Thanks for looking!
