Custom PHP Voting for vBulletin

I need a voting system for a contest with over 200 entries on a vBulletin / vbAdvanced site. I need to narrow it down to 100 entries, then 50, then 10. Needed Information for each entry - Entry Member: Member - Entry Name: Name of their entry - Entry Description: Description of entry. - Rating: (Ask Member to "Rank" if they haven't yet, Show average votes and score after they vote) I ONLY want Members of my site to vote for each round. Remove losing entries based off lowest ranks/scores and reset counter for next round of voting. Could be setup like this? 1=not so good 2=sounds good 3=good 4=sounds very good 5=sounds awesome! Then offer up 5 radio buttons for 1 to 5 next to each entry. Members would go through and input their rating for each entry. Then after they input all their ratings they can submit to the database? They can only submit ONCE per round. Then next round for 100, then next for top 50? So I would need the results cleared, and reset voting for each new round. Removing lowest scoring entries. I am using vbAdvanced and vBulletin 3.8.6 This is a one time contest / voting system.
