Need for 2 logos + A4 + enveloppes + B cards

Hi, I have a need for 2 very basic Logos. First one is based on the name CONCORDIA It is a company selling all kind of electrical stuff mainly for buildings, a lot of lighting, design lighting as well, but also all kind of DVD players, usual HIGH-TECH stuff. We don't really want it to show too much "electrical". We want it to show more into the Building/Construction business with the feeling of SOLIDITY, TRUST, DEEP ROOTED Greek column or else could be a good start. Second one is based on the name STELLAR It is a web-company (designing websites, managing websites, creating designs for them, possessing websites etc...) So we need a logo that makes a connection between: FUTURE / SOLIDITY / STARS / HIGH TECH Once the logos are chosen then just do the very basic stuff; A4 (letterhead) paper B. Card Envelopes Maximum payment will be 50 US dollars. Good luck and thanks in advance P.S.: Once chosen and created, the files will need to be given in several usual formats (eps, psd, jpg etc...)
