At this point, do something that does not scale. That means "Engage 1 bar and work with them". Sure you could say why not multiple bars at the same time. But that will be over optimizing which you don't want in the beginning.
Get your very first client by talking to them manually, showing them everything manually and get them to believe that your service will provide value to their business and help them make/save money either quickly or in long run.
Once you have done this successfully (which majority fail at), then you can go to Step 2.
Steps 3-infinity are all good only when Steps 1 and 2 have been done, rinsed, repeated with at least 30-40 ? clients ? May be more ? Depends on your industry. But before you get these many clients, don't bother with anything else.
I am doing this right now. Telling you from experience. Remember, a successful business is not about awesome software, automated stuff or any other fancy stuff. A successful business is about :
1. Aquiring customers
2. Retaining those customers for as long as possible which means keeping them happy.
Of course, doing the fancy things like a great design, automation are important but not at the stage you are at.
Hope this helps.
