I found them by sheer luck through a Linkedin referral page, and after a few email exchanges with Charlene, quickly knew that she knows that program intimately, and I felt quite comfortable giving them the responsibility of handling my project remotely from almost 7,500 miles away!
Among other things, my project involved a complex merging of a two very different website CMS and databases which they did creatively and promptly. Further, they also successfully attacked a wildly complex integration of mass amounts of content from an ancient version of WordPress into the customized installation.
As far as responsiveness: Charlene & her team keeps communication fresh and meaningful. I highly recommend them for any job. All the best.
