Converting Light Wave Studio format to FBX format

We have 3D files along with animation of a man and women wearing a dress in Light wave studio format. We need support in converting into FBX format without losing any animation. It is a conversion and rework process. Totally 3 men characters and 2 women characters. Supported software to open source files - Light Wave Studio 2015. Once completed, there is another project in extension to this, which will be given post this. Need it urgently in 1 day.
