Welding help needed at local miniature railway

Saw this and wondered if anyone here could help (or know someone who could?)
request for welding help

Nigel Ridgeon says:“
Mizens Railway interested to hear from any localish #TIGwelder willing to do us a cost-effective repair.
Our #CME Geoffrey Ian Shirtliff has sourced and set up (see pictures) two engine cradles to give access to the problem on the Mizens steam loco #Alice.
So now we see, in 3rd picture, the #leaking foundation ring of this copper-boilered loco.
#TIG welding of the copper foundation ring could fix the leak and get Alice back in Mizens operations in 2018.
Pls share this post with any friend you know is a #qualified #TIG #welder especially if they’ve worked on boilers. Thank you.”
