Not to pour cold water on the OP's idea but you are going to need more than just a scanner and web/graphic designer occupation to impress around here. What about colour fidelity? What will you be using to ensure accurate colour in your scans, what spectrophotometer and software solutions will be implemented and what will be your ambient light policy? What monitor will you be using and what's it's gamut and indeed does it even cover the entire Abobe1998 RGB range? Does the scanner? How may bit resolution per colour channel and so on?
These are the sort of technical issues you are going to have to address to work with any professional photographer shooting on film and then you will be up against drum scanners with highly competent operators that are scanning at far higher resolutions than 7200 dpi (optical, not interpolated).
