I'm assuming you're in the US, look up the prices for vinyl fence on home Depot or Lowe's website. They have pre build items for that type of fence. I would 2-2.5x your material estimate to account for labor, markup, and misc items that are needed. Removal and haul away of a chain link depends on what it looks like now. All in I would guess $4-5k if there isn't much custom work.
I would say that if you are physically capable and have the time, fences are pretty easy to DIY with a shovel, level, and drill. there are plenty of resources online showing you how. And make sure to call your local dig safe number.
Worked really well for me, just put in an API key to actual budget and it pulls all the info from simple fin. Only thing that doesn't pull for me it categories of the transactions so you have to manually set them up in actual but it does allow for rules.
