Hi everyone,

At the moment I am developing a website where I will sell lists of information about companies.

For this, the customer will need to tell me what type of economic activity, number of employees, income range he needs, etc.

The problem is that there are over 600 different economic activity classifications. So I'm thinking about the best solution regarding the user experience.

So far I've thought of 2 possibilities:

1) Create a huge form
2) Create a system where the client will input what he needs step-by-step

What would you suggest? The site is in Wordpress. Any plugins/solutions that would fit better in this case?

Thanks alot for your time!
