I'm trying to pull specific data on the industry, looking at the big players (companies doing over $1 million a year) and haven't been able to find an SIC or NAICS code for them.
Did you ever figure out what the codes were? I am in the same process
Whats up guy's I do not know if you found it already but this is what I came up with in my search....
Web Design = 541511
Web Hosting = 518210
Hope this helps.
