You could sub-let her pussy to a shop and make a profit!!
Just kidding, good luck with it mate. I've heard of plenty of those kinds of arrangements going bad, but always with girls from Phils or LOS where there's an attachment built, either through language being less of a barrier or through the guy making promises about the future. If it's a shorter term deal (one month max), tourist visa only, and the dollars are negotiated up front with no further expectations, it could well be worth your efforts. Let us know how you get on with it eventually.
