The viv is ok but there is things you will not need, heat rock is a no no, can burn beardies, heats mats are no use for beardies, you will also need a uv tube 3/4 the length of the viv and a controller to power it.
If I was you I would stick with Tom, very enthusiastic keeper and viv builder, he knows his stuff.
Here a link on the basic setup, these guy are over in Northampton and can build you custom vivs.
