Buy-and-build financial modeling help?

I'm early in my industry research and am thinking through the longer term financing approach to a market where you'd be taking a buy-and-build approach of making a series of tuck-in acquisitions.

I'm beginning to think through the financial modeling of that model (e.g. tradeoffs of funding acquisitions through more equity financing, debt, or more slowly with cashflows) and imagine someone has done this modeling exercise. Anyone willing to chat me through how you thought about it or share any templates?
