Boosting to silver/gold

Hi, i am a lol player that is in bronze for a long time now, i have that games that i am going realy good, and my teammates not, then i try to carry the game (most times we lose), and sometimes, i got the games that i am feeding... (and i always try to not blame my team...)
If someone gots the time to free boost, then i will be happy, if you want some money for it, i will try to give it
