Most insurance companies can recommend firms that do nothing but refurbish electronics equipment that has suffered smoke damage.

If it is a computer, any reputable computer repair firm can run the innards across their bench, cleaning boards and burnushing contacts as needed, and insuring that they hard drive hasn't been damaged, or copying the data from a damaged drive to a new or refurbished one. Again, ask your insurance folks, or look in the yellow pages for any large city.
