I was so pleased with the last trigger Clint and his colleagues developed for me I asked where I might leave a testimonial. They directed me to here. So, for the record, here's my approbation of these guys:
I was OK with v6 but less confident with v7 so I've used Clint for a few triggers, some pretty complex, and am VERY pleased with the results, even more so with the explanations that have come with more recent triggers and, through all our association, they've been generous with backup support and preparedness to tweak the triggers they've provided.
Bottom line: you have a trigger problem? Be assured these guys will get you over the line
