Although I have no specific experience with the ModX framework, I browsed the documentation on their site and am confident I can realize your brochure as a ModX site. My partner and I are 4th year computer science / graphic design students who are taking the year off to pursue our passion by starting a web design company. We've been designing and developing web sites with php, HTML, and CSS for over 10 years. In that time, we've done similar conversions based around other php frameworks and also developed an in house framework that uses some of the same underlying components as modx (particularly prototypeJs and TinyMCE), so I have no doubt we'll have the same success using ModX. Please feel free to contact me if you would like to see some of our work and I hope you give us the opportunity to bring our experience to your project.
