Realistically, if your lawsuit is with the person who has been acting as your agent in the United States, small claims court is probably not the right way to go.
If you are owed less than $10,000 (possibly including attorney fees), you probably need to hire a lawyer to pursue your case in the non-Small Claims Magistrate Division of the District Court. Lawyers are allowed in this forum, unlike the Small Claims division which is oriented towards pro se parties (i.e. people without lawyers). Small claims can consider only claims up to $4,000 against defendants in the county where the lawsuit is brought, and attorneys are now allowed in small claims court. (Source)
Even if you can be in the Small Claims division of Magistrate's Court, the enforcement of a judgment if you win requires technical court documents which are essentially the same as those for collecting a judgment from any other court.
Even when Zoom participation is allowed in a court, usually the main trial can't be conducted entirely remotely so someone needs to be in the courtroom representing you for the trial. (The only U.S. state where there is an actual right to participate in a civil court trial remotely is Alaska.)
A lawyer will also often be more effective at negotiating a settlement, with or without a mediator, which would avoid the need for a trial at all, and mediations these days since COVID are routinely conducted remotely. Mediation is often required before a case goes to trial.
If you are owed more than $10,000, you probably need to hire a lawyer to pursue your case in District Court (outside the Magistrate's Division). (Source)
It is also possible in District Court (not the Magistrate's division) in some cases to resolve the case in "motion practice" based upon submitted papers, rather than in a hearing. This is not really a possibility in the Small Claims Court or the Magistrate's Division.
Also, to be perfectly honest, the kind of case you describe is probably beyond the capacity of even a college educated person without legal training to do right and not screw up.
Handling issues like service of process, the rules of evidence, and the collection of a judgment are all highly technical matters, and there may be legal claims related to possible misappropriation of funds that you might not know how to raise. Depending upon the language of your contract, the other side may even be able to demand a jury trial which is far beyond the capacity of an unrepresented person to manage, even if they are only doing it to force you to hire a lawyer. It could also be necessary to use the "discovery" process or subpoenas to obtain records needed to prove the case.
For what it is worth, Idaho lawyers are less expensive than lawyers in much of the U.S., and Idaho is not known for having overcrowded courts the greatly delayed schedules, however.
