Yes, measuring larger properties can be time consuming. You can take someone with you to split up the property on large sites. Buy a foreman breakfast on a Sunday morning and knock it out. We are working on a relationship right now with goilawn. I just want to be sure it works well before endorsing it to our members but it seems real promising, especially for the larger properties.
Also when you measure, it's real important to develop time-saving techniques like measuring one thing and multiplying it by all the other similar measurements on the property. You really do get better and faster as you start doing it more often.
Happy New Year!
