Can someone help me find a hassle-free, decent paying job for an ex-con? Criminal history has left me unable to pay for my wedding now for 3 years, so I'm a fiancé who needs a job.

There may be many faith based programs in your area, that meet your needs and provide referrals for jobs, and housing for those that have served their time. Where are you?

First you do the wedding you can afford, if you can afford a 100 marriage license and a 50 dollar preacher there is no reason you can't be married.
So don't blame things not happening,

As noted there are often faith based programs that help with job training,

So what degree do you have, HS, BS, MS??
What was the crime, there is a difference between drug possession and armed robbery
What training do you have.
And what do you consider good pay ?
