hi, knocking any time of the year you will get custys, just depends on how bad the weather is, u need to work out what is the miminum you need to live on a week,
after you have done that work out how much a house is, dont listen to a lot on here saying they have a min of £10 as depending on where you are, you might/might not get it,
then get out and knock, and take any job you can, use the first 3 months as practise and after 3 months refind your round to the best jobs you have and fill them areas in,
sometimes it is better to have a load of cheap easy jobs in one area than driving around all day using fuel,
above all knock, knock and knock
