My closest thing to $59 is just a strait nuke and pave, with no saving up data and no setup of programs.
I personally think your leaving yourself open with this one.
I will never N&P a system without an image first. Even if the customer says the data isn't important it could bite you in the long run if you wipe a system and the wife relies shes lost all her wedding pictures. They could hold you liable.
I charge a flat rate of $130 for a system and $195 for a server for a N&P. I base my pricing on my hourly rate. I charge $65 an hour and charge 2 hours for a system and 3 hours for a server. This includes complete image of the old system if possible that I hold for 30 days, Reinstall of the OS (Windows or Linux) restore of there data including email, favorites, documents, and other data. Sometimes this required converting data for upgrades (Example: outlook express to live mail) I also set the system up for the customer on site including internet, printers, etc. Each system also gets all updates and activation taken care of. I will even install one or two of the customers programs if they have the genuine disks available. This includes office or quickbooks or something like that. I will not install an older game on a newer system for the flat rate price. I have had problems before with this. Like installing NFS Porsche on Windows 7. Nightmare, lol.
For the service I offer I think I am dirt cheap. Most N&P's take me well over 5 to 6 hours including setup time on site and I only charge 2 hours.
I always quote a job before i do it and I almost never go against my quote. I feel that if I diagnosed it and i am wrong I need to eat it and take care of the customer. The only time i will rise the price is if other hardware is required. However I always call and get it approved but in cases where I miss diagnose something labor stays the same as quoted. Even though my quote is based on my hourly rate the customer knows what they are going to spend. This is not flat rate pricing but its not just a blank check ether.
The only true flat rate I charge is $39 for a diagnostic, $130 N&P, and $195 virus removal. The virus removal only applies to badly infected machines. The price is based on 3 hours and if the fix takes less time i only charge for the time spent.
