Hello!
I am a graphic designer with over 10 years experience in designing all manner of branding, identity, and marketing collateral. As such, brochures are a mainstay of my studio's work.
You do not state how many pages or panels the brochure has so that has me a bit nervous! But I like very much that with very few words you've told me that you have everything ready for me to use in developing the brochure. That's crucial to staying on point with getting a project completed on time. I've also noticed over the years that my accounting industry clients tend to be well-prepared, so I'll give you the benefit of the doubt!
If time is of the essence for the project, knowing in advance how much material needs to be included would be very helpful. Often, the greatest challenge is fitting all of the needed text.
My basic process is to (1) hear what you need and see what I've got to work with, (2) quickly work up a concept for your review, and (3) based on your feedback create the full layout, submit it for your review and comment, and then finish with corrections or last minute changes.
Working this way, I've found that completing a brochure goes very quickly and feel comfortable completing the project in 3 business days.
I look forward to hearing from you. Please let me know if you need further details of my qualifications or if you would like to submit further details for my response.
Thank you!
