This is a fantastic service. Booster spoke frequently with me over skype, was very professional and dedicated, completed the boost EXTREMELY quickly, and was accommodating to even the minor requests (such as keeping summoners on appropriate keys for lower chance of detection).
Even with that handicap, he played like an absolute god compared to my Elo, and it was for the absolute lowest price I've ever seen.
If you're looking for a Boost, and you're in Silver, there can be no substitute for Doomy/Rebecca.
