Currently doing a Gold I to Plat 5 boost for me. He's been a pleasure to deal with so far, I will post the completed picture when he's done but so far 10/10. He stays in contact while boosting your account so you know exactly when/how he is playing.
It has been a slow process, he's only played 1 game in 2 days and never replies when I ask him what the deal is on Skype. Still a decent booster though.
Just a note,
I assume he will get to your job. He told me he'd get to mine, and never started until the next afternoon. He did explain he's just had lots of customers and not enough boosters. Didn't matter that he got to my job a day late, I didn't care at all considering how cheap his prices...
