We switched to organic fertilizers 3 years ago(SoundGro) with one app of a synthetic fertilizer in late fall. I never mentioned it to our clients. They like the results and the reasonable cost. I don't think they care that its a biosolid and I figure its better then an all synthetic program. We recommend other services, aeration, overseed and top dressing but most customers will only go for the aeration. We plan on offering compost tea this year although when I mention it to people the reaction is always "what's that?".
What's wrong with better? Not perfect. Less chemicals, more organic.
