be aware that if you ask for a quote, the person giving the quote needs to build everything into it as people in general will not pay more. The quote contains costs for things that may possibly not be needed but as mentioned, if the job does need need these "things" the customer wont want to pay and will say ÿou should have quoted for it"
If I am asked for a quote, it is ALWAYS more than if the asked for a guesstimate. The cheapest way is to tell me to go ahead and do the job. That way because Im being trusted, I feel the need to to the best job I can for the cheapest cost.
I simply prefer to give a quote because I will make a lot more from the job
Just something to think about
