Well I have done a lot of research and tested many online booking software.
The best solution i found that can install into my website is from Chatwing.(yes the same Chatwing chat room software provider!)
The Chatwing booking solution covered everything i needed including both text message and email new appointment confirmations. You can also choose to send client's text message and email appointment reminders both 24 hours and 1 hour before appointments which is very helpful, the controls are there to choose both options or only 1 of them.
I've got the blower fan mounted on the air assist mounting from Thingiverse (https://www.thingiverse.com/thing:2545095 - which I need to modify slightly) and the fan is connected to the top of the laser module. It is quite effective and there isn't any smoke damage on card or wood like before.
If you want to connect the blower fan to the laser module as I mentioned in a previous post, make sure you take some ESD precautions when handling the module. The four screws are self tapping and go through the laser mounted fan to the metal heatsink. You don't want to undo these screws more than once, otherwise the threads in the heatsink will foul.
The cable to the blower fan can be desoldered at the terminals on the fan body, cut down and resoldered, to shorten it.
