Graphic Designer for Marketing Collateral

We're a marketing agency seeking a freelance graphic designer to refresh a set of existing commercial real estate leasing brochures. The goal is to modernize the look while keeping all existing content, structure, and copy exactly as-is, with no rewriting or re-sourcing of information. We want a cleaner, punchier, more sophisticated feel: generous white space, smaller editorial-style type, and contained boxes/cards in place of large solid-color blocks, taking cues from polished financial-brand aesthetics. We need three distinct design options applied to the same two brochure pages (a cover/hero page and a data-heavy page) as mockups for client sign-off, delivered as editable source files. Once a direction is approved, we'll roll it across the full brochure. Please include in your proposal a quote for the initial three-option mockup phase, a projected cost to apply the approved direction across the full brochure, and your estimated turnaround. Experience with real estate, financial, or corporate marketing collateral is a plus.
