Any help is highly appreciated....

You have asked a huge (scary!) question. The biggest problem is most likely that your scan is likley all triangles; it is a gigantic problem because 3d scanner apps are not 3d animation apps; the first is always triangles, the second always quadrangles.
There are programs that a focussed on solving the triangles-to-quads retopology. The best (imho) is 3d Coat. Blender can do this retopology, but it will be a lost weekend for you.
If you are going for a quick solution, then your best bet is to import your mesh into a 3d animation suite like Blender (eg).
After that, create a Makehuman mesh that is as close as you can get.
Export that Makehuman mesh into Blender (eg) --normally on a different layer--and begin the manual process of aligning the topologies.
