Recommended body shop

Morning/afternoon/evening all

I am new to the world of MX5.  How much fun am I having…

I bought my ‘Elvis’ at a bargain winter price.  But the rust is terrible. 

As we are heading into winter I am looking to getting this sorted.

Any recommendations the in essex/london border. My postcode area is IG10.

Thank you all in advancd    This firm seems to have a good reputation and on their welding page the prices are displayed. They are near a railway station !  

Mx5 doctor did my MK2 sills a few years back and they are near Southampton
