Aluminum boat trailer welding question

So I was at boat show today looking at new shearwaters and noticed on the trailers they had boat buckle tie downs on them just like bass boats. Mine can only use the tie rod brand style which always comes loose while trailering down the road. This is because there is nothing on end of trialer to bolt boat buckle down to. Well somebody has done this now and looks and works so much better.
Anyway is there someone in gonzales who does good welding work like this?

Here are some pics to show what I'm talking about.

This is my trailer currently


And this is new shearwater trailer
