If you've never done safe work or manipulation before, you won't learn it here from reading a post or two. As tornoto said, there aren't any cool tricks to tell you over the internet that will open that safe.
As already said, make sure the locksmith shop you call does safe work and knows about basics like manipulation, some places just drill a safe before trying to crack the combination.
There is a trade organization called SAVTA (Safe and Vault Technicians Association) you can find someone in your area who is qualified and can give you a proper quote before starting any work
http://www.savta.org/savta_tech.phpThis shop seems the most qualified for the job but is 90 miles from you in Hayward, WI
http://www.billslocksmithinc.com/This shop isnt listed with SAVTA, but it is close to you, so it is worth getting a quote from them:
http://www.tru-lock.com/services.htmlif you still want to post a photo of the safe, you can upload it to
http://tinypic.com/ and then Copy/Paste the link in your reply here.
good luck,
