I think 2 things that can sum this up is it depends entirely on if its a indivdual or company. Companies will take longer than indivduals because of other work, its also down to how you manage your time and client expectations.
For example a job that takes me 5mins to do may take James 1 hour, where as a Job that James could do may take him 2 mins and myself 2 hours.
But the point is at the end of the day the time is illrevant.
Because lets say we both charged the client £30/hour.
James can do one job better than I so does it in 10 mins and charges in 30min slots so £15.
I then do it in 2 hours so charge £60.
I charge more for the same work but because James got it done faster has in fact just devauled his work, not neseccarily because he charged less and got it done faster, but because he knew what he was doing/a better way of doing/experiance of doing it before, actually means he is better than I at it, but got paid less for doing it because he devauled his time by saying it was a quick fix. It was only a quick fix because he was good at his job, otherwise it would have taken him 2 hours, meaning it wasn't a quick fix at all.
What then happens if James has another job on that takes him 3 hours? The clients expectations are now that it will be done quickly and be done in 5mins, so when he charges £90 even through its worth £90 the client is like but thats 6 times what it was before I'll go else where, when James could have done it to exactly the same standard, now if he had upped his self worth, and this is the key its not about ripping people off, its how much your services are worth, to £30 on the first job he would have got the second as the clients expectations wouldn't be so high, as then its only 3 times as much not 6 times more. Sorry for using you James for my nemesis.
Honestly don't look at it as in how fast it can be done because you then devalue your work and in the long run will find your self actually having less business from return clients and the crappy clients that companies off load, had one of them last week and my boss phoned 6 seperate web companies to off load this nightmare of a client, and if your clients don't want to pay let them go else where don't then charge less. You will be surprised how many people come back after a bad experiance of cheap services.
But from experiance clients who expect the world on a stick will cost you more in time just sending emails back and forth then you would make. So you also need to factor in client stupidity. For example:
Again 2 different clients ask for the same thing, one sends around 200 emails confirming it the other 3. How much time have you spent writing emails? Was that factored in to the price?
Now think how long it took to respond and write all 200 replies?
Was that time factored in?
When you look at it in time worth and job worth you can see how 3 days actually isn't really a long time and is pretty quick?
Have you just devauled your services?
I had one for my dads site recently, actually contacted my dad wanting to know who did it as there was no link on his site so your thinking in the bag and when I quoted for a site as good as his, he didn't want to know, but wanted all the bells and wisthles for £100. So he went else where, because there are free website builders that will do it for you. Yeah wont give you a site as good as my dads in a million years, the differance between a bagatii and a 10year old ford focus. But again client expectations where its cheap.
Don't devalue your services, that way you get good clients over clients who expect the world for nothing.
