Money Tree will accept webmasters from Croatia. You can make money with their dialer ( very good ), free cams ( very well, too ), paysites ( $38 per trial ) and per impression program ( haven't tried ).
BTW - some programs that have written in their TOS that they don't accept webmasters from Croatia, may change their mind and make an exception 4 you, if you show them your sites or get in touch via ICQ.
