Hello
I have to make a comment and hope you read it before deciding on a direction. You mentioned Apple in a comment. Apple always had an apple as their logo, and they are technology company. An apple doesn't reference technology, not one bit. You don't need a logo depicting exactly what you do. You need something memorable, unique, simple and something which can withstand the test of time. Don't make the mistake that everyone does when choosing a logo, by trying to put in there every refference to what their company does.
Thank you
Alex
