Prices are negotiable, but this is a general outline of what I think the time is worth.

TFT Boosting:
Iron 4 to Bronze 4- 1,000 FG
Bronze 4 to Silver 4 - 1,460 FG
Silver 4 to Gold 4 - 1,660 FG
Gold 4 to Platinum 4 - 3,060 FG
Platinum 4 to Diamond 4 - 4,726 FG
Diamond 4 to Master - 15,000 FG

Coaching -
1 Hour first session is free for players under gold 1 rank ( Tips appreciated).
Coaching after, is 800 fg/ hour or 2 vod reviews (This should get you up to platinum rank from my past experience), Unless we make a agreement on another amount.
