Considering you contacted folks who asked for your stats and didn't reply I would suggest you meet him first for 1 or 2 hours, take him out to dinner and if you get along with him ask him how much he wants for a week with you in X place during X dates.
Having an overnight as suggested by @MscleLovr would be ideal but if you're saving your pennies for a week and wondering about budget a 1,200/1,500 overnight just for testing might be too much. Your call!
Again overnights are ideal but I would stick to the guys you already met. What if you make things less complicated and simply talk to them about a week together?
