give yourself up to a week to make sure the item is working properly and meeting your expectations. there is no easy choice here. remember take the bad out then put in the good. and then the poop hits the fan. let me address the second part of that question first. i would recommend to start with couple of hundreds, between £500-£1000. the process will be required to be completed by june 30th 2013. our company can show up at the scheduled time with all the appropriate resources, and will work together with you through the entire job. we can’t prepare for tragedy and loss.
