Fix issue relating to online bookings system

An online booking system hosted at twinkleclean.co/booking is not displaying the total price correctly.

The one bedroom one bathroom flat to be cleaned with no additional services should be £115 but it is showing up as £150. Something in the PHP code is not working correctly. See attached.

You can test this by entering the following postcode - W6 0JY, and entering any date. Please also enter a valid email to be presented with the final booking step which displays the incorrect total.

Also, a cron job has been setup to send an email to anyone who doesn't complete a booking after 30 mins. This doesn't appear to be working after the code was migrated to another server.

I would like a fixed price to fix this- shouldn’t be more than a couple of hours work for a skilled PHP developer. I project managed the build of the system so I can point you in the right directions in terms of finding the relevant files on the server, etc.

James
