Hi Kathy,
Before hiring a researcher, you'll want to check the significant online resources available for Jackson County genealogy.
The County Clerk office has a online index of all marriage records for the county -
http://www.jacksoncountyclerk.0catch.com/ .
The USGenWeb Jackson County website -
http://www.rootsweb.com/~arjackso/ - has many resources.
Also, the USGenWeb Archives page for Jackson County -
http://www.rootsweb.com/~usgenweb/ar/jackson/jackson.html - has almost every cemetery inventory currently held in book form at the library, and many other records.
Good luck!
