Logo design for Audio Visual company

We would like a logo for a new / rebranded audio visual company. The finished artwork will be used on the website: http://www.isisav.co.uk as well as on business cards and business stationery, and possibly also on liveried vehicles. We have some ideas, but would love to see you guys use your imagination & skills on this one!

ISIS Audio Visuals

We need a logo that is clear and sharp - certainly easy to read - for an audio visual company based in Oxfordshire (UK).  The company name is Isis Audio Visuals, and the main logo needs to read either: "ISIS Audio Visuals" or maybe just "ISIS AV".  The 'ISIS' part doesn't necessarily have to be in capitals - we would welcome your ideas & input on this!  There will be a strap / tag line under the main logo.  We haven't finalised this yet, but if you could please work on the basis of it being: "AV Services & Support" that would be good.

We will require the contest winner to provide 3 files.  One needs to be a smaller file size for the web page, one needs to be high resolution for printing on business stationery, and the last one would be a file to print from a mono laser printer (i.e. black only) when necessary.

The company provides audio visual equipment to corporate and educational clients in the United Kingdom, and so we're looking for something smart and stylish.  Equipment is supplied and installed as well as hired out.  Please see the website if you would like more background: http://www.isisav.co.uk

One idea we have had is for the word 'ISIS' to be outline text, with the inner part of the characters blue and rippled like a river.  For your information, in our part of the world (Oxford, UK), The Isis is a river.  But if there are other meanings / interpretations of the word ISIS (Egyptian for example) or if you can work in graphics relating to projection or presentation equipment, then we'd be very interested to see your ideas!

- Simple, clear & effective please!
- Colours preferred would be red, white & blue
- We would like ideas please - and will give feedback on them

- We don't want this to be too intricate or fussy - it must be possible to read the text without any confusion.  We would probably prefer something simpler.  We don't want lots of different colours, and if the design can also work when printed on a mono black laser printer when necessary, that would be a plus!
