What is the problem? Is it that your feet come off the floor before the desired pressure is reached? If so, just go to the bike shop and test out a few of the pumps. Don't know if that's possible in your case or not. You could get a small compressor and use it. I have a battery operated compressor with a digital display that you can set the pressure on. That would work but it would not be handy to carry on a ride.
