How to transition from Conversation to offering and sale

Hey guys, this is Armin I'm the newest member of Circle. 

I just had trouble making smooth transition from regular conversations to offering my service or sale. 

Just wondering how you guys do it? That doesn't look awkward and out of place.

For example you message a store owner and talking about their business and I ask them do you have a website? 

And when they say "No" I don't know how to offer my services the way that doesn't make the Conversations drown or awkward. 

Any help would be greatly appreciated 🙏
