Hi Darran.
Good to see things are so busy for you mate. I think the vids are good. I think a USP like your guy's accent is a good thing. To get him to go viral would do wonders for your hit rate on youtube. I just have a couple of helpful pointers if you don't mind.
Are your vids embedded on your website? Your link from your youtube channel needs to be more prominent if you can somehow. Have you optimised each video before uploading them on youtube?
Just to professionalise the vids, could you add an opening and closing credit to them with a call to action, your logo, website and phone number?
Steve.
