"I am not to worried about the amount of work available as a whole. I am more worried about the nature of the work available, which will be increasingly skilled."

This is the same thing, FWIW. Opportunities to use skilled labour rely on the existence of skilled labour capable to fulfil it. The reason is that skilled labour shortages push up the price of labour, and that reduces the viability of businesses that use it as an input, and thus reduces the number of opportunities advertised.
