lol It was indeed a typo. Thanks for catching that ^^ However, if I'd not been play with my wife and taking my time about it maybe it could've been possible... BRD gets stupid fast invites. I watched many BRD friends pass me long ago... they would always ask for advice when they were lower than me... then in 1 month they would be 75 and quit the job. Not very many people really enjoy BRD and there are very few at 75 that make it their main as a career BRD. I can count the level 75 NA career BRDs on my server on 1 hand. Most of the others are crappy BRDs that leveled it as a second job for their sky shell and suck horribly at it.
As for soloing the mini-primes I would almost say don't. You say that things like Elemental staves and Morion Tathlum are expensive for you... (FYI I sometimes farm as many as 6 Morion Tathlums in 1 sitting) so the solo fights are going to be frightfully expensive and horrible frustrating for you. Me and my wife like to adopt-a-newb ocassionally and every time we get one that wants to become a SMN straight away... they quit very quickly after losing the minis over and over and spending forever farming the gil for yag drinks and ethers and such.
If you were on my server I'd have you come along and leech the avatars. My wife and a friend trio all of the avatars frequently and my wife does Fenrir about 2 times per week. I suggest leveling your BLM up and then you can easily get a spot in a PT going to do primes.
