No introduction, kinda hard to say without knowing at least a little bit about you...
First question...
--Do you have a signage contractors license?
Then...
--Was it worth it then?
--What kind of signs?
--Are you talking design, design build or the build/install?
In my opinion, not really worth it unless you are licensed and can handle large projects.
(5-10k design jobs, 50k+ sign jobs)
