You need an electric trimmer. My brother owns a Core brand Li-ion battery powered string trimmer. It is a serious machine and it is not a toy like electrics you find in the discount stores. It has a breakthrough design motor and has tons of power and run time. Check out the link below.

I have a Stihl KM 55 RC-E . The head unit has a spring to assist in starting. Very easy to start. I have had mine for 9 years no with no problems. Its expensive but I learned my lesson after purchasing the less expensive brands at big box stores only to have them last a couple of years.
