8x4 pixels...that's the funniest excrement i've heard in a long...well...EVER!!!
There's no way you can possibly get am "official" school logo with the information given...
1) 8x4 pixels doesn't work.
2) For offial print, paintings, t-shirts, letterheads, murals, etc, etc, etc you MUST have something in a format a printing company can work with, and something scalable.
3) You have to know what to ask for, and obviously you don't.
HINT: Go to worth1000.com with a couple hundred bucks and offer the logo up as a job and you will get hundreds, if not thousands of fresh entries to choose from.
