The least expensive way of Russian learning is learning in lingq.com
You can use a lot of my Russian courses for beginners here:
РУССКИЙ С НУЛЯ- Russian from zero(95 lessons)
БАЗОВЫЕ МОДЕЛИ- Basic patterns(54)
ПЕРВЫЕ ШАГИ- First steps(125)
НАЧНЁМ- Let’s start (41)
НАЧИНАЕМ ГОВОРИТЬ ПО-РУССКИ- Let’s start speaking Russian(54)
You can try my course ‘Russian from zero’ using this link:
What’s about a tutor - you’d better start by yourself and after study of the base of the languyage, you can find a tutor here or in Itaki.
But in any case you have to study Russian every day to be successful in yout lerning.
Good luck!
