The OP has been contacted directly about this:
Whilst we welcome agencies posting job vacancies at ROVworld.com, we do expect posters to follow our guidelines.
In particular, for job vacancies, please read: http://www.rovworld.com/ftopict-2356.html
The best approach is to compile your vacancies into one post, not create multiple posts as you did. Multiple posting is also against forum guidelines, therefor your all but one of your posts have been deleted by an admin.
You are welcome to post your requirements once more, but I strongly suggest you combine your requirements into one post and add more contact information.
