Hi. Fortunately, this time no one is going to be reminded of a Criminal Minds episode. ;-)
I generally like this iteration, but think you can do better in both the text and in your current photo options. At the very least, take a camera on your next hike and take photos of one another, lots of them, so you can have one current pic of each of you to send, along with whatever travel photos you have of the two of you together.
As far as the written portion, Looking For is currently more of a list than a narrative and therefore isn't as charming as I know you can be. And in Additional comments you've so emphasized how difficult it is to plan things with you that you've done a fine job of discouraging all but the most persistent. I don't think that's in your best interest, especially as you venture into the previously untapped arena of swapping and want the widest possible range of choices.
What if you just say being caretakers for an elderly relative means you need to stay nearby and aren't as free as you'd like to be? It has the advantage of being true without signaling that you're mostly unavailable, which is what you're doing now.
I hope other people comment too, so you get the widest range of responses. Good luck. ;-)
