I want to start to collect old rifles from WWII and before, But I'm needing a little help getting started.?

CMP. Join a gun club that participates in the Civilian Marksmanship Program. You will be able to buy excellent military surplus arms at reasonable prices. You will need to meet the age requirements and other laws of your state, but it's a good source of reasonably priced WWII rifles. As with any used firearm, be sure to have a gunsmith check out the gun before you attempt to shoot it.
