For how much it cost's for a bag of plaster, pva have a look on ebay for some cheap tools (i picked up some used tools marshalltown gear for not alot) it well worth ago at worst you'll have to get a plasterer in.
I've done the same as you although our property is smaller i fancied having ago at plastering and started on two walls we was knocking down they came out not to bad so moved on to the smallest bedroom.
now completed that finished two larger walls in the other bedroom and done my first ceiling tonight getting faster and more confident with each bit i do.
I bought a dvd which got me started with the basic's followed that and getting there slowly...
(happy to send the dvd on to you if you think it will help)
