Web Search and filter

What is the best design way to do this?

I’m creating a web form to receive input. The input data will be stored in the database and then a search is done over three web services for some corresponding data.

Is it correct to create in one model all the fields from the initial input and the three fields of information I will receive back form the web services search? Or should I create a new model for each web service data I receive back?

Once I get the data back I’ll then need to validate specifics from each service.
