Well, to be honest, there are not much options for you.
1) You either need to buy it in Georgia and use DHL post, which then you need to pay for post which is not cheap.
2) ask some other Iranian to buy it for you, then reimburse the money to them using some international exchange currency companies.
3) ask some exchange currency company to do the transaction for you in Iran, although I am not sure if all currency exchange companies do this stuff.
