Process for settling a sale with a cash deed purchase where seller is out of town?

[William Smith]

I am talking to someone about purchasing their lot but we are about 250 miles apart my question is how to process the sale so both buyer and seller are satisfied? Do you have to hire an escrow agent or maybe have the sellers relative that lives in town get her notarized cash deed and get the cashiers check at the same time sorry I am new at this part any help would be appreciated.
