Deck replacement company recommendations

Our deck is rotting and boards are cracking and falling apart. I was going to replace some but really need to replace most of them. So I thought I’d maybe swap out to composite boards so they are a little more durable. Apparently I’d need a permit either way though according to the permitting office. Whether I knock the whole thing down or just swap the boards out doesn’t matter I guess. The sub structure appears mostly good with a couple rotten parts I would repair. It’s like 300sqft total with steps and everything in that.

I’m wondering if anyone has a company they would be reasonably priced for this or experience doing it themselves with permitting and the drawings and if they can give some advice on that. I have had some drawings done up for other things but it normally costs a decent amount. And they were new structures. I don’t know how I’d get drawings for this exact structure that already exists since I’m not touching most of the sub structure.
