Hi, I am looking for excellent and very creative logo designers who could work with me on a long term basis. Please only bid if you agree with the following points. 1. You could supply 4 designs initially with in 12 hours after a project is actually assigned, and offer unlimited revisions. It must be noted that I need all the revisions with in 12 hours after it has been communicated. No exceptions on this. If you fail to deliver with in 12 hours, I would assign it to someone else as I am already sick of the time-wasters. 2. I would offer 30$ for each individual project. Price is fixed. Please only bid, if this is acceptable. 3. You must be accessible via skype or any popular IM. 4.
