might be, might not be...
you would have to deal with client's demands, expectations. travel to and fro to collect film and deliver scans...
labs charge under $10 for cut film at 1800 x 1200... with colour correction and CDROM thrown in. for the same price can you deliver similar goods?
let's say you take 3min to do a scan + tweaking... 36x3=108 or slightly under 2 hours.
your time and fee calculations probably is different, but as long as you can justify it, go ahead and try lor.
or you can charge say $8-10 doing a very good job scanning individual frames at hi-res.
