I NEED ANY JOB

I am looking for any job.
I have extensive experience in working as a car mechanic - without documents.
I can work in any profession.
I come from Lagos Nigeria and would like to find a company that will allow me to start a new life with my fiancé in Ireland. For this I need an employee visa. Is there a company that would send me an invitation to work and help me get a work visa?
My English is perfect.
