Hi and thanks for reading this.

We are a small software company with an email encryption and zip compression application. We would like you to design us 3 icons (2 variations each) that convey the following:

1. Compress file attachments (function on, and off off)

2. Encrypt file attachments (on and off)
3. Encrypt the email (on and off).

Vista styling is preferred, but we're open to anything that most clearly communicates these functions.

Besides the adobe illustrator files, I'd like to get the icons in ready to use format.

The icons will need to scale down to 32x32.

I've been all over internet scouring icon sites, so I generally know whats out there. We haven't seen anything that exactly addresses these functions as a group.

Good luck, ask questions.

We really need these icons quickly, so the sooner you get your entry in, the better. I reserve the right to close the contest early.

I'm generally open to paying you via virtually any method, including Moneybookers, as long as the fees are reasonable.
