Hiring a scripter to make a timed racing quest

I have a dragon riding game and I already have the dialogue system fully made and scripted, so you would solely focus on making it so that once the dialogue finishes, the player has to go through all of the rings IN ORDER, and depending on their completion time, it tells them that they got ranked Bronze, Silver, or Gold.

Again, I have the ring asset already made and the dialogue system made so you only have to focus on the player getting through all of the rings and getting their time and ranking
