if you aren't getting paid for 2 months then 50man including key money and deposits, 2 months rent, 2 months utilities, startup costs blah blah blah then 50man sounds like the minimum you should be bringing. JETs normally only have to wait 3 weeks before their first pay cheque. To be honest your current job sounds ghastly. You'll probably make more cash ditching the sub teaching malarky and do some casual laboring or a retail gig.
