There are much better places to find suitable (legal) employment --- for Turkey at least (not the best of countries with regard to the ESL market in terms of salaries, benefits, et al.) Namely large training establishments, nation-wide, which are reputable within their respective field.

Better pay, better working conditions, more qualified and experienced staff, which you won't find with small outfits like this who are not well-established, and whose demographic and target market is pitifully small.

I wouldn't recommend working for these clowns.
