Hi man. First of all let me start with the fact that it is not easy to get a working visa in Azerbaijan. Due to low employment of citizens government is not interested in attracting foreigners, especially to the work which can be easily done by any local.
However, there ARE some people working here, especially the ones that come here as a student, but do consider that Baku is extremely expensive city and pay is not that high. You have no idea how the living cost is compared to Bangladesh. Thus, unless you get a license/diploma and find a proper job here, I dont think there is valuable point to leave your beloved ones behind to come here...
