With about 4000 hours heavy helo in my log book, SAR Commander, mountain flying, instructing and HEMS, I would tentatively suggest the 1000 hours in a Robbo or a Schweizer aren't going to do you a great deal of good in the current climate.
The industry has died a death over the past decade. Glimmers of light are appearing with BALPA attempting to regulate T's & C's in the UK but it is a long time coming.
By all means get the hours but you would be better off trying to get into a gas turbine helo at the earliest opportunity followed by multi engine. Quickest way to a job! Experience is king!
Best of luck, sorry to seem unhelpful but I got out of the Helo industry as it died and was sorry to leave but the fixed wing world is still where the money is.
