Is it permissible to work at a gas station with lottery machines and cigarettes to raise money for a mosque?

I was doing a job at a gas station here in Calgary until I saw your fatwa regarding working at a place where lottery machine and cigarettes are there; so i stopped working there. The owner of the station requested me to come and work as soon as i change my mind. Now we, here in calgary, are in a great great need of a mosque and alhamdulillah, have got a plot too. But we still need to collect 50000-100000 until May 15. So now since we are in great need and are compelled, so can I again work in this staion only and only for getting money to put for this holy place? Will my money be halal?
