Purchasing California Land from Owner in Switzerland; Notary?!

[Duke George Brady]

Land located in San Bernardino County, seller located in Switzerland.

Having trouble finding info here and on U.S./Switzerland government websites about getting the proper Notary that can be recognized on the Deed.  The U.S. embassy offers a service, to a $50-$100 charge, but that's only in Geneva.  Motivated seller wants to make as little effort as possible, aka a notary closer to them (currently reading about the Hague Apostille Convention; trying to connect the dots and hear some real world experiences).

Anyone else buying from distant, unattached and motivated owners overseas?  Delinquent taxes, international taxes/fees on top of County charges.  Feels like a decent market already...

Also, any advice on best ways to transfer funds would be appreciated!  We're only talking several thousand max for two parcels.

cheers!
