I hired the business to do fall fertilizing and overseeding at the end of October 2010. I've paid money upfront as a business owner asked.
Overseeding was done the next day, however I found a quality of the job very low for many reasons.
Fertilizing has never been done, even if the business promised to come and do the job at least 5 times. Now the business owner stopped returning my calls.
I would not recommend this business to anyone. If for any reason you still want to work with them for Gods sake don't pay them a penny upfront.
