Do you know where you want to go (location or even a program)?
Have you told anyone in your program about your plans?
I wouldn't worry about a PGY-1 spot, you should be fine going for a PGY-2 with your rotations. Whatever program takes you may need to juggle a few rotations here and there to get you what you need, perhaps.
The APA has a clearinghouse for open positions. Talk with your local psych PD, and any psych residents you may have worked with. If you know your local psych attendings, that may help further, though it's a little questionable as to whether you'd want a letter from them.
Best of luck!
