Crowdfund/Automate Presale?

I have a token that is pretty much a clone of safemoon, but with a different use case.
The presale has already begun, and we have generated a decent amount of money so far, but every transaction has been manually filled.
Is there a crowdfunding source code to import the tokens source code, to automate the transactions? Or is there a bot available to take care of all transactions that come in.

I am pretty much looking for something where someone sends BNB to our wallet, it will automatically send the proper amount of tokens back to the investor, until we officially launch the token.

Any info would be greatly appreciated!
