Oops... OK, my hands are up and I'm standing next to the wall. Are you ready to shoot me now or I'll have one more minute?
Abd, I'm giving work away if I'd like to test somebody. I always use one and the same design for testing and this is not paid. It helps me to compare the designs and designers' skills. After that when I give them a job I know what to expect as a quality and time. The design is in PCAD but if you are interested, we can take this conversation offline and discuss a few details.
