It can be done alone, but it will take longer. Basically decon every glyph that you loot and farm mobs that drop glyphs (such as zombies).
Best way is to have another player that you can swap glyphs with. I'm guessing this is your first character that you are working with on enchanting, but if you do decide to level up additional characters, it's easy to do solo since your character that is maxed (or close to max) in Enchanting can make glyphs for your other characters to decon. This is great because you can make blue and purple glyphs at the highest potency you can craft and your other characters will get more inspiration than they would from dropped glyphs.
