Background employment check

ok guys my question is about the background check on employment, I worked for a company that did not take out taxes so at the end of the year i had to file as an independent contractor... i worked there for 5 years ( bartender/bar manager ) the problem is that with that job which dates back to my start date in 2003, they changed hands/names a few times and then closed down in 2008. because of them not taking out taxes i did not get w2's, they arent in business now, so how will acheck verify that employment? I dont want something so silly to knock me out of the opportunity with the company. I am trying to go ahead and get all information together for exact dates so i can make sure im accurate on everything else... I feel like i am applying with the fed's after reading the background check stuff... LOL

What happened with your situation Tonia? They seem not to play about the verification process!
