I have looked at your project a number of times and I am intrigued - this is not the normal type of work seen on here so I just had to make a bid!
I am UK based and can turn my hand to most things, I taught for ten years so I'm good with people, I've worked in retail, restaurants and customer service posts in the past and alongside my writing I also babysit for families within their home or at hotels.
My bid is for 8 hour day so £10 per hour but can be negotiated depending on requirements. I'd be really interested to find out more details of what you need and whether I can be of any help? Please message with questions.
