Working out shift Patterns for a 14 hr/365 op

[andyxs]

I am looking at starting off two Coffee bars in two city train stations (same city close together and connected very well) and have been looking into shift patterns and staff numbers. I want them open from 7am till 8pm (actual staffing time 6:30 - 20:30 for opening and cleaning) 7 days a week including bank hols as the train stations are fairly busy the whole time. At least in the initial period I am going to have them manned by two people at a time. This covers for any illnesses etc as well.
I was thinking of two shifts 6:30 - 13:30 (7hrs each) and 13:30-20:30
this bit I am fairly confident in as I have ran places myself but never two simultaneously and not 7 days a week so it is staffing numbers that is confusing me. I,e rotations that cover weekends and holidays - How many staff for essentially a 14hrs a day 365 operation.
I would like full time ish employees and I am going to be paying slightly more than the going rate in the hope of keeping staff and they will get worked hard in peak times (£9ish hr).
The other option I have if it proves to be quieter than expected is that I have one in each booth all the time and I float between.
Does anyone have any good software, At the moment number of staff required is key for the tender. I want to do this right and if I can't do it for the right money its not going ahead.

I would have a 30 minute hand over period between the two shifts to cover late arrivals (especially in London) or other issues.
Can't just have one lot going without the others being in or informed of any issues.

Very true cheers, this will be the case, any ideas on week by week patterns?

what do you intend the normal working pattern to be for 'full time' staff 5 from 7 ?

presumably doubles will not be the norm or only be allowed on the last shift before rest days becasue of the 11hour break rule ...
