Now I have a better idea of your requirements I would say that if you don't get another offer of an aircraft by June, Big Red Kite may be by then in a position to help you in September.
Expect the cost to be IRO £60/ Hour + VAT dry and plan on a fuel burn of 23 Lts/ Hr.
Use your hour building wisely, it may be the only chance that you get to enjoy your flying, go on a long trip south aiming to fly no more that 3-4 hours a day, leave the GPS at home and use DR navigation with the aim to be within 60 seconds of the ETA at waypoints. This will hone your skills to the point that the CPL skills test will be easy to pass.
I am guessing the ultimate goal of this is to join the Red Nose airline ?
