Can't you just pick any random prime q between 2 and p-1 and then q and p-1 are automatically relatively prime? Or do you need to consider any relatively prime number as potential numbers to pick? I think I would know how to do the above but I would have to look it up (last semester I took a cryptography course and we did things like that)..... If you can't figure it out then let me know and I'll look it up.......
