Hi!
I'm MikroTik Certified Trainer with most MikroTik certificates (MTCNA, MTCWE, MTCRE, MTCINE, MTCTCE, MTCIPv6E) on the "trainer" level, and around 9 years of experience with MikroTik routers and wireless links.
You can "check" me on my last MUM presentation ([login to view URL]), or looking for the older ones on tiktube.com. You can also see my jobs history on my Freelancer profile (all jobs were MikroTik-related and all customers were happy :) ).
If you check my videos from MUM presentation - you'll probably notice, that I'm quite familiar with MikroTik scripting, so the script you require would be quite easy (that's why the price is relatively low :) ). I worked with more complicated ones - yesterday I made a script downloading custom files after MikroTik initialization - and doing "autodestruction" (disabling itself) after successfully doing it :).
Regards,
Daniel
