Finding a hacker!

I’m trying to find someone to change a plugin for me – it is the popular ‘Booked’ plugin. What I am trying to achieve is for the client to be able to change the price required for different appointments. But my search for hackers is not working yet. Any top tips on how to get programers to custom a plugin? Anyone out there willing to look at it? (if so, please respond here). Thanks, Matt.

The plugin is documented here:
