Let's get down to work, shall we?

Let's get down to business.

Let's cut to the chase.

Let's get the ball rolling.

Let's start. Let's begin.

-------------------------------

LET - 

Let me begin/start

Let me start by saying ...

Let me start with a joke ...

Let me introduce myself ...

(Let me help you, show you, ask you a question, explain, be clear, finish, interrupt, know, tell you a story, call you back later, give you my e-mail address, give you my phone number, spell it, pass, buy you a drink, see, take a selfie, get this straight)
