The most cost-effective method would be to utilize software that allows you to immediately load and link your data to an electronic catalog (assuming that this process would not require any special knowledge or further preparation on your behalf.)

The more you depend on external staff, such as web programmers, for transferring your data into a catalog, the more expensive the procedure gets. Try to make sure that no manual procedures are necessary for data integration. This is especially true for links and hotspots.

In the ideal case, a non-programmer should be capable of doing revisions all on his or her own.
