do I offer a detailed list of services that surpasses the current guy and hope for the best.
This is my vote!
If they are actively seeking bids, my guess is you won't need to go 10% less, but a promise for better quality at the same price. You know they are willing to pay it if they paid that price last year.
Think about this, I assume they are not satisfied with the service they recieve, so why would you ask for less to do a better job than the guy before you? I'd throw in a 1 time extra and keep the same income as the pervious guy if you know his number. On the other hand if they are looking for the lowest price, wouldn't you rather spend your time on an easy to ratain client?
Mini Marts always have traffic, cars hanging their bumpers over the curb, shrubs to mow around, islands, ect.. There is more risk for you kicking up a rock and busting someone window, more risk of making their clients mad, but then again there is more traffic to get your company seen too.
I'd personally take the easier place to mow, but that is what I'm interested in..
