Help me edit simple youtube videos and post them and finish editing my WIX site

Hi, I'm a life coach and have recorded a series of videos on a range of topics. Most videos are 5 mins long and I need to create thumbnails and post to my youtube channel and website with appropriate tags and SEO optimization. I'm tech savvy but just can't get down to editing them myself. There are about 10-12 ready videos, this could be a one off project of a couple of weeks or we could look at continuing too. I would like for the person to work with me at least at the start and then complete work at their own space. So Mumbai based freelancers please.
