*** SOLVED ***

I knew from the outset this was going to be somewhat complex and daunting, particularly if you haven't had any exposure to Transport or Logistics. So, ( Not that I came to the decsion lightly as I would not normwlly do this ) as time was running out, I approached Claus directly for two reasons.

1. My limited Time-frame involved
2. Large amount of back and forth traffic

Essentially, the two main reasons I am here replying and closing off this post is to firstly, publicly proclaim my utter gratitude to Claus for his amazing dilligence and patience in assiting me with his amazing talent in resolving this epic endeavour given he had zero understanding of just what it was he got himeslf into with no knowledge in the area I operate in; it was very humbling for me, even after all my attempts to recompence him, he brushed it off citing his happiness to assist me.

It is heart-lifting to know there is a global community of like minded, generous people willing to go the distance for a total stranger half a world away.

Now, for the second reason; I thought it fitting that Claus' hard work be put on display, so that anyone who happens to need something similar in the future, they need not look any further that this awesome peice of code:

Eternally Gratefull to you Claus!

Cheers
Mark.
