Candy Bar

So after seeing the candy bar at TWOTY I think I want to have a candy bar at my wedding but I need some help for you guys ......

1. How many jars would I need for a wedding of between 150 and 175?

2. How much candy do I buy?

TIA

I was going to do this but it just became something that was too much, and got tossed to the way side...
I would do 10 types and some other stuff, like a lollipop display or some candy bars or something. They say you should do like 1/3lb pp, but it's hard to say since some candies weigh more than others. I say buy the bags you want, then go to some candy store and fill it like you would at a wedding. Multiply that by your number of guests. And when buying candy, keep the size of the candy and the weight of the candy in mind.
