Dont think telling every one you were sacked from last job is going to help your situation.Seems you have some experience in a few aspects of cleaning.
Hope some one in your area gives you a chance to prove yourself or at least give you an interview. I was sacked from my last job (no fault of my own i must add) now working for my self and loving it .they since offered me my job back and asked me to complete an application form in case my wee project doesnt work out.
I MUST ADD I LOST A LOT MORE HAIR!!!!
Good luck in your job hunting.
