Need help hanging a picture frame securely on wall

I'm looking for a handyman to hang a medium-sized picture frame in my living room. The wall is drywall, and I’d like to avoid damaging it. Please assess the best spot, locate studs if needed, and use appropriate hardware. I have the frame, piercing hardware, and a level ready. If possible, please provide advice on weight limits and mounting options for future heavier artworks. Friendly, reliable, and tidy work preferred.
