What method do you guys price small raised beds at? I've had quite a few requests for prices & wanted to simplify the estimate process for the labor part. For the most part they are straight beds using that 1ft long textured block you can pick up most anywhere. Most are between 50-100ft total length, 2-5blocks high. Prep site & install. Any specific formula? how do you guys do it, per block, for a given hight & length? How much?
