looking for Lightroom presets for portraits, weddings, HRR etc.
Don't waste your money. Work your way through Lightroom Tutorials by Julieanne Kost and learn to use Lr properly.
I agree with John. After learning LR, you can make your own presets; this is much more rewarding than buying presets as they are your creations and you know exactly what they do and how they work.
