HI @ankushkatiyar, thank you for being here and my apologies for the delayed response. Personal accounts and organization accounts are entirely separate.

On April 14 we announced that our free plans come with private repositories and unlimited users, so you may just want to create a free organization account first:

Then if you would like the additional paid features, you can upgrade to the Team plan which costs $4 per user/month for any user account that has access to a private repository:

I hope this helps!
