Looking for an host family in England

Lately, I'm at home every day, and I'm seriously thinking to move of moving to England for a couple of weeks or more. Nowadays, English knowledge is very important to find every any kind of job. I'm considering I think that an host family is the my best chance for me because I would be in contact every day with people speaking english. Could Can someone suggest tell me if it can would be a good solution, and I can trust it if it's safe? Thank you.

I also appreciate any correction. :)

I'm in the U.S., but I'd be open to the possibility of a visitor if you're not set on England. :-)
