How to bid in a foreclosure Auction, for US citizens overseas?

[Khalid Al-Rasheed]

Im interested in buying properties cash without financing, through foreclosure Auctions in Arizona. 

However I'm a US citizen living and working over seas, this provides an obstacle to obtain cashier checks and be physically present to take part in a bid at the courthouse steps. 

Which brings about the question, How then can one appoint an official representative,to bid, pay and collect a title in my name, and on my behalf while im overseas to conclude the deal bid to finish all 100% remotely from abroad? 

Thanks in advance
