30K is very low for a Hawker job. Might be the going rate for a RHS job but you should pull at least 6-7k (tax-free) a month in the left. Beirut is fine. Cosmopolitan lifestyle but it's expensive and there are vastly different levels of places to live there. Make sure you've got that tied up & post the suggested living arrangements for comments. Taxis aren't that expensive - driving is a bit crazy, especially if you're not used to life over here.
The operation shouldn't be a problem; the handling companies are OK.
PM me if you need any specifics.
