i hope i'm not too late to be here, no conneciton at home :/

well, i guess you suppose can get some inspiration and headups from these cool awesome inspirational logo sites

http://logopond.com/
and of course a lot of useful articles and examples on major existing brands : http://identityworks.com/ (look at how they comment on visa's rebranding )

i learnt a lot from there.

my pov of your logo design, or probably my pov of how a logo design should be,
1. easy to be remember
2. practical, in a way that you can very flexibly reproduce it in many other format, etc...it will still look good in b/w or even colour. or even uses less colour if the company chose to print the logo on their namecards etc etc
3. learn from the best, and research more, look more.
