Pitching AR idea to local Business. Looking for Advice

So im currently working on pitching an AR idea to a local bar. Its a tiki themed bar and I have a working protype of AR drink coasters to show their drinks.

This is the first time I’ve ever pitched something like this to a business and don’t have much experience in it. Im working on a powerpoint presentation using this video made on 8th wall on how/what to pitch to brands. https://www.youtube.com/watch?v=RsPlQ64UDKk&ab_channel=8thWall

Im wanting to start a personal business creating AR content. Since I’m wanting to use 8th wall as my platform to publish content. When it comes to payments, should i be asking businesses for a 1 time payment for AR content, should it be monthly to help pay for the 8th wall subscription or should i breakdown my payment with a Statement of Work outline(SOW) like is shown in the above video. Being independent and only working for myself creating a breakdown SOW seems like a lot if its just me doing the work. If i do create one can anyone help in directing what the average $ per hour i should be working for?

Any guide in the right direction would be very much appreciated.
