Tax Accountant for income taxes

Hi,

I am new to forum so sorry if this is answered before. I am a Canadian Citizen who moved to USA in 2006. My wife is an American citizen and I have a permanent resident (green card). I am looking for an accountant in the USA (we reside in Alabama) to do our US income tax. I still have some assets in Canada and an open income tax issue with revenue Canada, so the accountant needs to be familiar with Canada tax issues, etc. Any suggestions of accountants or firms for working class (not wealthy) people?
