Russian language schools in St. Petersburg

[sbgskl.livejournal.com]

What is the best russian language school for english speakers in St. Petersburg? I'd prefer it to offer at least four levels of russian, starting from no experience. I studied a year of russian in university, but it's been so long, I'm pretty sure I should restart from scratch. I'd take one in the US, but I'd like to live in Russia, having traveled the country a bit after college (Moscow, and towns on the trans-siberian rail).

Sub-question: how difficult is it to find english-teaching positions in St. Petersburg?
