Restore WordPress Website from .tar File

I'm in need of a many review professional who can restore my WordPress website from a .tar file. TMD hosting prepared a backup after many tries with them Let me know if you recommend another host or can offer hosting on that domain. Traffic/Bandwidth is not significant.

In any case... A pro ASAP since we need to be back online in 5 days.
