Aluminum fencing components in BR?

Anyone know of a fencing supplier around Baton Rouge that would have components for a “custom” aluminum fence panel? Our backyard has a commercial style fence by Specrail, a national fence supply company which went out of business a few years ago. I need one panel (less than a panel, really) and one post to finish the fence after some work that extended the fence line by about four feet. I have found several places online where I could order the post, rails, and pickets that would be the closest match to our fence and I could assemble to match the rail spacing on our fence. (The rail spacing is the biggest issue with off the shelf panels- they are all a little different.). However, when I go to checkout, shipping is outrageous- like 2-300+ to ship one fence post, 3 rails, and some pickets. I assume it’s because they are used to shipping large quantities of material and use freight companies rather than retail shipping companies.

That leads me to ask- any companies anyone knows in the area when I might be able to purchase and pick up the materials?
