Need help with elevator

My team is working on a robot that we have already completed the drivetrain for. we have also made a mobile goal pickup that still needs some fine tuning. Now we need an elevator system for our intake system to connect to. We would like the elevator to be able to reach up to stationary goals, and it would be best if it extended straight up. Can anyone help?

This is a very vague plea for help. Could you possibly post some pictures? If not, height is a very common problem with elevator lifts (other than speed), so you may not ever be able to reach the top of the stationary goal.
