I have been in landscape biz for 6 years and last 4 with more hardscape. I recently bought out biz partner and am running the biz solo now. I have been second guessing my estimates last year and this. Profit margin I feel could be slightly higher. I do a lot of custom work with diamond block and anchor--curved lines, patios, walls, etc. Want to get others input on what they charge for hardscape in STL to make sure I'm on the right page. Last advice I got was a few years ago and at that time industry standard here was $30/sq ft. I'm originally from Cali so not many contacts here. Any input appreciated. Thanks.
