There's always the option of assigning two teams to a single student. I've seen teams that had their scouts watch an entire alliance. However, I think it would be more beneficial to work with another team.
We've done this in two different ways. You can either work together at the competition, scouting together and then making copies of your sheets so you both have them. The problem we've run into with this is that you have to use the same sheet. This requires one of your teams having to learn a completely new sheet (if at a later competition), or making a combination of the two. We did this at the Michigan Championship where two fields made things quite interesting. It was definitely nice to have a larger scouting force, and we'll probably end up doing it again this year.
The other way we've worked with other teams is by having a scouting meeting together. We scouted individually throughout the day and then came together that night. We compared notes and gave teams a letter ranking. Then we made our own pick lists separately. This was nice because we had two separate pools of data. If there were glaring inconsistencies, we could go back and figure out where we went wrong as opposed to just assuming our information was right.
I would suggest reaching out to teams that are in your area and will be at your competition. Under your circumstances, I think scouting all day with another team would be more beneficial, but either system works.
