Premium print-ready brochure design for European oxygen–hydrogen enriched water technology

I am looking for an experienced graphic designer to create a premium, print-ready two-sided brochure / flyer for RevitaAqua, a European oxygen–hydrogen enriched water technology. The brochure will be used in the USA during visits to holistic clinics, functional medicine practices, longevity centers, wellness spas, medical spas and premium wellness environments. I will provide the real product photo and the complete English copydeck. I need help with the visual layout, typography, supporting graphics, icons, and print-ready preparation. The desired style is clean, elegant, premium, scientific-wellness and high-end — suitable for longevity clinics and premium spa environments. It should not look like a cheap supplement ad or a heavy medical-device brochure. Deliverables: US Letter two-sided print-ready PDF with bleed and crop marks A4 version Digital PDF Editable source file Confirmation that all images / graphics used are commercially licensed Before creating the final version, I would like to see 2 different design directions: premium spa / wellness style clinical longevity / science style Could you please let me know: whether this project fits your experience, what similar brochure or wellness/medical design work you have done, your estimated price, your estimated turnaround time, and what source file format you would provide? Thank you.
