Well they have 2 weeks to get their gears. If they do enough lvl 4 missions, getting the 84e shouldn't be that hard. But they'll have to go chip-crazy if they want decent mods.
If they do Albertal quests for vet polishes, they can easily get lvl 100 pio armors. I recommend doing this because you only need 1 lvl 100 chip to get good mods and you can just buy myst powders for each armor (so it'll be like spending 13~14m vis per armor -- cost of lvl 100 chip + myst powders).
