We spoke to a few different companies as we set out to find someone to create a website/database application to augment our desktop software. We chose The Demski Group in part because we found them very easy to talk to in our interview. That first impression stuck as we have a great relationship with them now. We are currently planning to farm out another project and are not even considering looking for anyone else to take it on.
