Cut and weld small rust patch on Sprinter van roof

I need an experienced panel fabricator or automotive welder to patch a small section of rust on the side of the roof gutter channel of my Sprinter van. The van is fully drivable, so I can bring it to your workshop, factory, or home garage. PreferabIy within 30mins drive of Burleigh Gold Coast. • You will need to cut out the dead metal back to clean steel, fabricate a small matching sheet metal patch, and weld it into place. • The Finish: Please grind the raw welds flat and flush so it is structurally sound with no pinholes. I am doing the rust-proofing, priming, seam sealing, and painting of the roof myself, so you can hand it back to me bare and unprimed. • Requirements: Must have experience welding thin automotive sheet metal without warping the panel. Gas-shielded MIG or TIG preferred (no messy gasless flux-core please). Looking to get this done as soon as possible. Please mention your relevant automotive or sheet metal experience when bidding. I have another van that needs weld work too once this is done.
