Goddamn, this is one thing they need to fix in FFXIV. If you make it so people need to party, make it easier for them to hook up for chissake.
Personally I find Level Sync to be the best thing they ever added- it's not much easier to get a party than this. Really, you could just grab 2 friends you know and just FoV all the way to 75 if you really wanted to.
What's the best way to make money in this game? Selling stacks of crystals is rarely getting me any money. I'd be lucky to be able to sell them at 1000 gil per stack.
Save up any beastman seals you have, or turn them into the guy that holds them in Port Jeuno (Forgot the name, Shami or something), eventually you'll be able to use those to make money.
Before then though, I'd recommend bees. The bees on Zegham Hill of North Gustaberg are a pretty good place to farm (Along with goblins and bats). Beehive chips sell for 3000 a stack, honey for maybe 3-4000. If you're not from bastok, Crawlers in Windurst drop silk threads which are rare drops but sell for about 10k a stack, and they drop crawler calculus which can be turned in 3 at a time for 600 gil + some fame. I'm not sure about Sandy though. Unless you have a security token (And thus have effectively 60 slots of inventory with the satchel), space can be a bit of an issue if you don't manage your equipment well, so you might want to save some gil and get a bigger bag sometime soon.
And for people who haven't seen it yet, the POL site just announced another update is coming in late July (Which probably means like the 30th or something I'll bet), and it shows a picture of winter lands, so I think expecting Glacier (S) and Xarcabard (S) wouldn't be unreasonable.
