Logo for Startup Audio Visual Company

I need a logo designed for my friend's new Audio-Video-Lighting Company. Its a brand new company and they are just starting to print marketing materials. I convinced him that he needed a professional looking logo, and with the brilliant group of designers from 99designs that was possible, even on a shoe string budget. His budget is $300 total, so we're splitting it up for logo design and there will be another contest for the design of the business card. The winner of the logo contest will most likely be awarded the business card and stationery commission as well, but at the very least, you'll get first crack at it.

We are looking for a simple, but "fresh" logo that may or does not have to include AV and lighting equipment.

Graphics you might incorporate into the design:
- Microphone, instruments
- Can lights, tracklighting
- Speakers, sound boardThese are just ideas to spur on the creativity, you may use some or none of them.  Any combination of the three aspects of the business is encouraged. However, knowing that you have a better eye for this than we do, if simple manipulation of the text looks the best, we won't pigeon-hole your creativity.

Primary focus of this business is running the soundboard for different events, as well as designing and installing audio systems for Churches, Schools, and similar venues, so nothing too over the top. 

Professional, but cutting edge is the key.

Need "printable" files.  PSD or .AI for the completed version.  .jpeg is obviously fine for uploading into the contest, but must be converted before final files are delivered.  Vector is not required, but certainly welcome.

Must be transferable into grayscale as well.
