Ask your local wall manager, if you get some one that actually cares then they will give you the run down on what works and what doesn't.
Personally I would start with a series of holds that mimics your project route or boulder and train on them. Use screw on smears for feet to build core tension skills and strength.
Secondly I would look for multiple uses, if you rotate your jug hold do you get a good sloper you could use for the future etc.
Be creative with wood from B&Q, just make sure you sand down the edges and make sure the curving edge is large. A small acute radius of edge will bugger tendons.
