Difficult situation Kirsten - but taking into account that you need the money so badly - how about accepting the job if/when it's offered and then looking round for another position? I know it's a mean thing to do - but-------needs and devils spring to mind.
It's quite a quandry to be in.
BTW - I don't think you'll have any problems writing the reports in English - yours is superb.
Good Luck with the difficult decision.
