As regards the possible commercial promotional aspect, why worry? Just tell them who you are and what you're doing, then give an honest and fair 'warts 'n all' blog report, so they can address any bad points quickly.
Who knows, they might help with your PL site running costs with a CSG Banner Ad (which is after all what you have in mind for local Paphos businesses, is it not?)
Go for it, please! Cheers- AL
