I thought your leaflet was okay. But if you want me to be picky

1. change your name because Scrimking relates only to trad as gazza says. Time and again when giving out leaflets people ask me what my name is. You might not think including your name is important but the customer does.
2.Call divert from your landline costs £1.74 a month so there is no need for mobile no. By the same token if your phone no relates to an area all the better. Play the local card every chance you get.
3.The bullet points should be followed by benefits. Fully ins is not a benefit, neither is friendly and reliable. Examples of benefits might be- frames and sills cleaned everytime,convenient payment methods, or stays cleaner longer.
But.... it's still better than my first attempt and I'm sure you'll get a good responce. Get delivering.
