Design a One-Page PDF Flyer (printable)

I need a professionally designed one-page PDF flyer (A4) for a financial research business. The flyer will be given to high-net-worth/retired investors, so the design must look premium, clean, and trustworthy — similar to professional consulting/finance firms.

What I will provide:

The full copy/text for the flyer
Logo and brand colours
A professional photo to include
QR code / link

What I need from you:
A print-ready PDF (A4)
A digital version optimised for email forwarding
A high-quality, corporate-style design that makes the flyer look credible and premium

Important: This is not a flashy marketing flyer. It should be professional, minimal, and elegant — suitable for a financial services audience.

Please share examples of previous corporate or professional flyer designs you have done.

I also need a full brochure designed with 6-8 pages. This will be a separate project.
