Best way to create 1000 IG accounts?

So im on a mission to create 1000 IG accounts. Trying to make it a relatively cheap process…

Do I use bluestacks and manually go through 1000 accounts?

Also, am I going to need to buy like 500 private proxies to create these accounts? (i know ill need proxies to run the accounts, but thats a different story). Does changing your ip from static to dynamic help you create IG accounts using different ips??

Thanks for your help in advance!!
