Editing cool video for our social media

Hi Everybody,
i run a fashion company and we're focusing on social media advertising.
We would make some video to post on our channels and need someone to edit them with effects, putting in our logos and easy text to explain the sense of what we do.
each spot may be 10 sec to 30 sec and this is something we would do every week.
We dont need a super professional cut, and our video will be made easly by iphones, as we like to give an image of seld made production.
CAn anyone help????
