It honestly varies greatly, it has been known to be VERY quiet, its entirely down to the demand and customer needs, It's not a full time job as I said it's just an opportunity to make a bit of money on the side from time to time.
UPDATE: Unfortunately my websites offline for a while as it is currently under review (a required part of the service from my provider I'm afraid) so if you need any information please PM me or email email@example.com
Website is now up and running again apologies for any inconvenience caused during the last few hours there were some problems with the hosting provider and the site was down during domain setup etc. HOWEVER its back online at the new address of alexseymour.org.uk
