ROS + Gazebo + RViz debugging, for Robotics Startup

I am looking for a detail-oriented ROS developer with working Gazebo & RViz experience to help debug some various issues in code being built. To start, we have an AR tag that does not detect very well. We think this is probably due to colors being off (not black and white) but there could be other factors as well. We have several more tasks we can use help with that are similar in size & difficulty. My small team and I are a small startup in the Silicon Valley, working on a robot for the home to do menial tasks. To raise money, we're working on a demo that can identify parts of the home, and trace the outlines of them with a robotic arm. This job will help us get to raising money sooner :).
