Um... There is a buying and selling area of this forum for a reason. Maybe try there?
You need to post this in the buying section of the forum. You should also include what you have for sale, with pics for proof... Typically a UGC goes for 20-25 life.
Please post in correct section.
Anyway, 10 dollar UGC's usually goes for 20-30 life.
If you posting in the trading section I'm sure you will get a fast reply
Depending on seller you can get life for .40-.50c each so you can do the math on how many life you can get
