I order online from Grizzly
I've heard good things about Laguna, but I have no experience with them. I do have good experience with ordering Timberwolf brand from Grizzly. I also weld my own blades in 5/8" wide and under. It's not a complicated process, and any good machine shop will have an induction blade welder, but they may not have "woodworking" blade stock on hand. The hardest/time consuming part is dressing/grinding the welded area flush with the rest of the blade so it will ride between the guides without "bumping".
I don't know how fast Grizzly can get them to you in these weird times.
The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)
