custom time delay relay curcuit board

I have a fairly easy project for someone who knows what they are doing with electronics...

Here is what I have...

down function) Relay sends out +12v - stays on

up function) Relay turns off 12v trigger.

So those are my triggers... +12v on and then off is off...

When trigger is +12v I need to output +12v on PIN1, and Ground on PIN2 for an adjustable amount of time, .25-2seconds (adjustable).

When trigger is removed, I need to output Neutral on PIN1 and +12v on PIN2 for a separately adjustable amount of time.

Voltages and such may change a little bit depending on the motor I pick up... but the idea and essentially the cost/difficulty should remain the same.

Basically what I am doing is triggering a motor in forward and reverse. Hope this makes sense... doesn't need to be super elegant... if you can do it on a breadboard that's fine if it works.
