Need help securing wall-mounted items in living room

I'm looking for a handyman to fix several items securely to walls in my living room. The job includes mounting a wall shelves, a tall mirror, and a lightweight framed artwork. Some walls are plaster, others brick behind the plaster, so I’d appreciate advice on the best mounting hardware. I can provide the items and their dimensions, as well as the positions I want. The ideal person will have experience with mixed-wall types, use appropriate anchors, and ensure everything is level and safely mounted. I’d prefer a weekend or early-evening slot, and I can supply the screws and brackets if needed.
