UAV ROS Gazebo

Hi, I am looking for experience person in ROS Gazebo who has worked on a drone model for path planning, mapping, control and localization modules. Especially if able to reproduce the existing code from open source repo. Once we have a standard system we will modify to our requirement that I will inform to the person. For more information please mention your past experience and level of ROS Gazebo. Price for the project will vary according to the work nature. However, I would expect a reasonable counter offer. If you have any github or open repo to show please cite your portfolio link for review. I will reply to the best persons proposal. Thankyou
