Can anybody help?

Need my safety devices R019 cage fitted ASAP can anybody point me in the direction of somebody who can do this reasonably cheap? South East but will travel
 
He want £1500+vat lol which I can get a full fia weld in made custom for that money, basically means my cage would have cost me £3300 all in! Lol
 
Got a company doing a full weld in for me up north next week called SW Motorsport, really reasonably too and it's going to be fia approved not just msa approved. Cheers for help guys
