Car rental from Sarajevo to Tirana

I think that it will be difficult to find an agency offering a one-way rental across those countries. For instance, Auto Europe had no luck to find anything that would allow me to drive a combination of Macedonia/Albania/Greece, with or without Bulgaria in the mix, for less than $1000 for two weeks. Try contacting an agent located in Sarajevo, such as http://www.sirius-travel.ba/en/, the tourist office itself, or these car rental listings that they provide: http://www.sarajevo-tourism.com/rent-a-car-eng.
