First, have a good chunk of change available for the next couple of months, as in $1500 to $2000 dollars. I would recommend P411 friendly providers who are ok with newbies. There are a few of them, and if you can get connected with one - and then see her a couple times, then she'll be more likely to 'ok' you to another provider.
K agencies are a lot tougher, and the fact they change 'owners' fairly frequently, you have to be a regular and visit regularly to stay in rotation. Pro tip is to remember the location of where you saw a girl, and if you let a few months or years lapse, throw out the location name and that will help you get through screening.
I, personally, never give out name and employment because of a past incident. Yes, I end up passing on some incredible providers - but its not worth the risk. If you do decide to give up that information, find a young lady who will meet you in person to look at your ID and do the search, so there is no electronic record of you sending correspondence to her.
Its a bit of work to get started, but once you're in and build a reputation, it will obviously be a lot easier.
The easiest way is to give up your real name and employment, but I wouldn't recommend it...but thats just me. Others seem to be more willing to give up the information.
