Graphic/Icon Design for Payroll & HR Application

We need someone to design about 50 icons, for our Payroll and HR Software. I will send to shortlisted bidders a DOC file showing some of the icons we need, with a few more coming soon; like Educational Records, Employee Movement, Medical Records, E-Leave Application, E-Claim Submission, E-Appraisal etc. We want XP-styled icons and you must be able to design them in a creative manner that appropriately depict the functions we want to display. They should be clean-cut and yet look vibrant. Please submit references of your work together with your bids. We need to award the order in the next 5 days, so please submit ASAP. As we don't have much time to shortlist the many bidders, those bids without sample works will be rejected immediately no matter how good you claim you are. Good luck!
