I have to agree with Karl - there are a lot of off-shore companies doing basic paper to CAD conversions.
More depends on what your local market needs are. There could be clients who want more than what
the off-shore companies offer i.e. field verification / as-builting. If the drawings are to be used for purposes
other than record / reference drawings the client may want a higher level of detail / quality. Some
clients have had higher expectations from the off-shore (cheap) route, than what was actually delivered.
Personally, I think it's a pretty good deal overall. The problem sometimes lies with the decision makers,
who either don't know enough about CAD, can't define their needs accurately, have their eye only
on the bottom line, don't recongnize that any savings they realize up-front may be spent later, when
the conversion drawings require a lot of conditioning to their own requirements. The best clients
IMO would be the ones who have tried the "cheap" route and know it's not cost effective for their
needs in the long run.
Also, a warning regarding copyright - there are people out there who might regard this type of
reproduction as copyright infringement, depending perhaps on the intended use of the finished
CAD drawings. I'll let someone else fill you in on these hazards and self-protection clauses you would
have to employ to reduce your liability.
