Randy,
The easiest backpack leaf blower I can recommend is the Dolmar PB-7601.4. 2-cycles always will present more start-up issues than a 4-cycle engine will. Dolmar is an amazing German company who is credited for inventing and patenting the first chainsaw ever. So to say they know a thing or two about small engines is an understatement.
To make life even easier, Dolmar has one of the most durable, and reliable "spring assisted" recoil starts on the market. It has to be felt to be believed. She will be running this with ease whether anyone is around or not.
