I have a friend who tried it twice. The first he found out later was writting 50 or so guys, each sending her $25-100 per month (about what he was sending) for family emergencies and the like, he later found out. That's about $2500 a month. He later "imported" a "model" he like better, but after she got legalized, she disappeared.
Just my 2 cents, but look in the mirror. Chance are if you like what you see, someone else will to. If you don't, fix up yourself the best you can.
Selfish relationships seldom ever work. So to find yourself a princess you must first become thier prince.
If that is too much, just remember (Eddie Murphy impression) "HALF!!!"
