Reasonable for a bit of extra money!
Projects are available on an ad-hoc basis so some months you won't make much at all but other months you can make more. You need to check the UHRS system regularly to take advantage of opportunities and confirm invoices online. Pay is reasonable for the nature of the work and some of the projects can be interesting.
ProsCan do at anytime from home.
ConsWork scarcity and sometimes there are issues with functionality.
