Don't panic! It's quite normal. I've rebuilt my brakes a number of times and I've found that bleeding the front callipers is a pain in the neck. It can take ages to get them up to pressure. Two tricks I've found are to wind the brake lever adjuster out so you get the maximum leverage and when it seems there are no bubbles coming out and you've still no pressure, take the callipers off and push all the pistons right back in again. Don't disconnect the lines or anything, just push the pistons in. I presume air gets trapped in the pistons.
Took me over an hour and a half once. Keep at it and it'll come good.
