Where in the UK are you? It would be good idea to include this in your profile as a likely source of help for someone in your position will be other Haupterkers (if there are any nearby).
Don't worry too much about software costs, the free edition of HW with the St Anne's organ should be adequate for your purposes and will run on a modest computer by todays standards. Bigger and more powerful will always be an attraction but if money is tight you can do without.
Similarly, you don't strictly need any kind of stop control hardware initially, just set up preset combinations on the screen and it's easy to trigger them with any kind of cheap MIDI controller.
As others have observed, it's the keyboards and in particular the pedalboard which will be difficult to source (or modify) cheaply - keep your eyes and ears open for anything that might be useful (especially a pedalboard).
