Converting Coordinates in a LAS File


I am a Costa Rican Sustainable Tourism student and I have been using D.D for a couple of months now with my DJI Phantom 3 , I love how easy it is to use and how solid and trustworthy it is.
The only problem I am facing is that I need the LAS file (Pointcloud / 3D model) to be in the Costa Rica coordinate system CRTM05 or UTM17 , If I manage to achieve this , I will be able to start my own mapping business.

I have been doing a hard research on the subject but so far I have not being able to do it ,I have been able to convert TIF files but no luck with LAS.

So , is someone out there able to guide me in this? I feel kindda lost after weeks of research.

Thank you.
