Our Wordpress website was customized and designed by Coalition Technologies.
Here are a few tips based on our experience (this also contributed to my rating):
1. All of their quotations are in business days. There's a difference of approximately 4 weeks vs 6 weeks if we compare 30 business days and 30 days. This was something I overlooked when we signed up. I thought the quotation was for 60 days but I realized that it was 60 business days (12 weeks). They were consistent in quoting business days throughout, so the miss really was on me for not catching it, so pay attention when you're planning your schedule / calendar.
2. They are efficient in managing multiple projects simultaneously. I have previous experience with another design firm that only did one project at a time. That meant that everyone was available BUT we paid that way too (probably 5x what we paid for the site). With Coalition, their dev / design / project managers are handling multiple projects simultaneously. This is not a bad thing UNLESS you miss a deadline on getting them the feedback / content that they need. Then you move back in line. This could cause a delay in your project, so do not miss getting them the info they needed from you to move ahead. Again, something that was our fault, BUT something we should have known on the onset.
3. They are really good at marketing of design and development. They provided us a lot of extra tips into what we needed to be doing from an SEO standpoint just by engaging our project manager in review of the discovery phase. When our site went live for about a month, there's a noticeable 15% uptick in organic traffic. Having been around for a few site migrations and launches, I've never seen an upswing that short after launch, so this is a major plus to working with Coalition (and the main reason they're 4 stars).
In summary- make sure include some extra time into the project if you know your organization isn't the fastest on turn around. Expect on having some delays beyond that. And if you hire them to build the site, take advantage of their marketing knowledge.
