With a small amount of funds it would not be a good idea to hunt bandits especially if you do not have a lot of health. Creatures on the other hand can be handled easily even with a cheap weapon assuming you are using a projectile weapon from outside of their attack range.
Honestly, when it comes to bandits or creatures they can be handled even when you are alone assuming you can control the attack range. What this one typically uses for creatures is a Bowcaster or two Relby K-23's and for bandits this one uses an A280 and attack from beyond the attack ranges of the enemies.
Though what everyone has said already is true as it would be much easier to raise some money, get equipped and then go hunting. And factions allow a nice source of income for the most part.
