I'm a diamond 1 player and i've boosted several friends before and i want to start to make some money with it.
Prices will be:
Bronze V -> Bronze IV: €5
Bronze IV -> Bronze III: €5
Bronze III -> Bronze II: €5
Bronze II -> Bronze I: €5
Bronze I -> Silver V: €7

Silver V -> Silver IV: €7
Silver IV -> Silver III: €7
Silver III -> Silver II: €7
Silver II -> Silver I: €7
Silver I -> Gold V: €10

Can maybe boost higher divisions if you really want, we can also make a deal about several divisions.
You can add my skype: Trafno2 for more details

 

try get some vouches from friends with screenshots to verify yourself better, its hard starting out with no proof whatsoever of being legit.
