Something has gone wrong

Hi Freelancers

My WP website https://swancleaning.co.uk has stopped working. Don't know when or why, haven't checked it for weeks, maybe months. There's a backup app running on it, reporting a backup every morning, but not sure whether that backup worth a penny or not. Might be attached or hacked, I don't really see the point of someone taking effort into hacking a worthless small-business service website without any importance or significance, but one can never know.
Please have a look at it if you can and tell me your price. We're a bit price sensitive atm, but this will have to be fixed anyway. Many thanks, Tony Banks
