You serious? It depends how much you really want to do this. Maybe i#this is your calling. The thing is you'll never know until you try.
As long as you don't make arrangements for the weekend of 30th September as I'm not available as I'll be at a wedding etc.
Seriously if you want to do it go for it just let us know & we'll figure something out. Hell even if its once a month I'm presuming this is strictly voluntary so there shouldn't be a full commitment as in employment?
