3 of us 5 hours in total, with coffee and a sandwich and loads of rattling.
I think we all agreed it could be done with 1 person in 5 hours though, an average price for this work should be in the range of £600 so I don't think they will be many takers with the amount of cheap anilines going to flood the market.
Learning how to do this is 2 fold, 1 is that you know how to do it and 2 is that you know when to do it (from a customer/business point of view) no point of selling this service to an Argos suite, you need to look for the better quality suites.
