Work around lookup drop down with too many entries

Work around lookup drop down with too many entries

Hi 

I have a Company Form and a People Form with a lookup so I can associate People with Company. (one to many relationship). But since there will be about 150 records in the company form, the lookup drop down would be unworkable. 

Is the only option to use Deluge scripts to associate the records with the ID field?

 
Thanks.
