Welcome to the forum. This area is for introductions which you did but maybe you can also post on our other area which is more for finding people in a specific area. You might investigate if there are poly groups that meet locally that you can find local resources.
As for avoiding scams and such... there's no hard and fast rule you know? If it seems too good to be true it probably might be. Don't let your hormones and your emotions get the best of you.
