Hi. My husband and I found a place in West LA called Family First. They have childproofing merchandise as well as earthquake safety stuff. I found that price does not vary much in this category and the cheap stuff will break easier (such as the childproof drawer stoppers, gates, etc...). The owner Lynetter is onsite at her store. She knows every product and is available for help and advise. I believe you can also make an appointment with them to come out to your house to asses childproofing. A friend of mine had her house done which included mounting bookcases, tvs, cushioning hard edge furniture, gates, etc..). http://www.familyfirstonline.com/companyinfo.htm
Best of luck!
