DuckRyder,
Look in the yellow pages in your area, and see if you can find anyone who does Ultrasonic Cleaning. Believe it or not, injectors generally clean up very well if dropped into an ultrasonic tank for about 15 to 20 minutes - in nothing more than soapy water. I used to sell the equipment to transmission rebuild shops to replace the solvent tanks. The ultrasonic waves will break up the deposits that may have your injectors "frozen"
