I would like to offer various IT services (from fixing nana's internet, and unbricking mum's phone, to building a website from scratch). There is a large demand from clients and many talented people hiding away.

There isn't really a marketplace for the general public for small jobs, on site, that are afforable.

And if it's not Really Easy to add a new Category, then perhaps I can offer my services :-) No seriously if it's more than a day to build and a day to test you need to create another ticket under Technical Debt
