After deciding against the Barnet studio, we searched online for other studios to see if any were suitable.
I emailed The Light Studios with this email:
They replied with this:
With the 10% student discount, this will bring the total for 8 hours to £148.50. So far, this is the best offer we have found and the price includes all the equipment listed on their website.
