The website builder cannot hold your business to ransom like this. Contact the website builder by email telling him to re-instate your site immediately or you will raise a court action against him for your losses. (You must be able to quantify your losses, so if you normally take £500 per week, for example..and £250 is profit...then your loss for one week is £250)
You can also inform him that he must fulfill his obligation to you to do A,B and C failing which, you will be forced to use another website builder to repair the website and you will pass these costs onto him. Give him 48 hrs to respond, then get someone else to sort it out.
You can also raise an action for recovery of the 50% deposit.
Hope this helps.
