Digital Divide Data provides data digitization services to researchers, by employing people in Cambodia (if I understand correctly). For a development economist, it appears to be like killing two birds with one stone. The service is used by Stephan Litschig (2007) "Intergovernmental Transfers and Elementary Education: Quasi-experimental Evidence from Brazil".
Structured Concepts is another data entry service company. Used by Donaldson (2008) "Railroads of the Raj".
