New Start In Germany

I am a 43 years old ex-flight attendant.A single lady.I was serving two airlines in the past 12 years until 31/12/2017.I would like to continue my career in Europe and I successfully got a job offer from an airline based in Germany.I would have started to work earlier if out of my mistake I would not have to wait for a document from my previous workplace for 7 month.By now I ren out of money to start over in Germany.It is very expensive and difficoult to rent an apartment there.If you don't have a rented home,you can not open a bank account,so they can not pay you...I would need 3000 EUR to restart my life please,If YOU can help me even with any little amount,I would appreciate it.Thank You
