I am currently operating a lawn and landscape maintenance company and I am currently looking into adding a waterscaping service. The company that we buy our mulch from is looking for contractors that are interested in installing water features. They are an Aquascape retailer. My question is what certifications are avaliable for this industry or training is avaliable for this. I'm sure that people have asked this question before and if anyone has a link for a thread already started on this topic could you please send it to me. Thank You.
