Logo concept ideas

I'm looking for some logo ideas for my new business name. The successful designer will receive a brief with more information but basically looking to have a minimum of 5 different types of logos to choose from. This job is purely to create concepts and choose a logo which may require some tweaking. I would like an EPS file. Any other logo work will be done as a separate job.

It is REALLY IMPORTANT that you attach your logo examples to your proposal - design work generates a lot of proposals and I need to be able to quickly see your logo work without having to trawl through every portfolio link. If you don't attach logo examples to your proposal, you are unlikely to be considered :)
