Hi there,your prep so far and expectations appear very good.Most of us have sold from home at some stage.I would say even though you will be part time,get a website ( inc. your photo,embellished CV,plenty of bulls....t),I like to get ideas from US websites-they have great wording.Warranties- you are right,these companies let you down,they can upset customers and be expensive.Do your own,we have fo 21years - it works.You will need plenty of advice,just keep posting on here. Good Luck !
