I had flat/inverted nipples...which I confirmed by doing the pinch test described on a fact sheet from LLL. I pinched them and they went *in* instead of out. I figured this out at about 8 months pregnant. They looked like "normal" nipples to me, so I had never suspected flat/inverted nipples until I saw the sheet and decided to try it!
I asked the LLL leaders of the group I was attending if there was anything I should do before the baby was born, to help prepare my nipples. The things I had read on the internet mentioned using breast shells (I believe Medela sells them) to draw out the nipple. The LLL leaders said that this was not necessary, so I didn't do it.
My dd *did* have issues latching. I don't know how big of a factor my nipples were and how much other issues contributed. At any rate, on day 3 of really no latching to speak of we started with a nipple shield (also made by Medela - Target sells them) and used that, on the advice of a lactation consultant. She warned me to start "weaning" dd from the shield as soon as possible, as there is the possibility that a) the baby will come to only be able to nurse from the shield long-term, which is a PITA and b) the milk supply *can* be affected.
So, after a few days of nursing really nicely with the shield, I would just feed her a little with it and in the middle of a feeding (when she was no longer quite so hungry) I'd try the naked boob. We did this more and more until one morning (she was not yet 3 weeks old) I just bit the bullet and decided to work with her and see if she could BF without the shield. It was a little stressful and her latch was not "textbook", but she did it. She is still nursing almost 2.5 years later! Yay!

Anyway, I don't know why you won't have access to nursing help after the baby is born, but that is worrisome. Besides flat/inverted nipples, there are many other common issues that could come up, and it's really important to have support and good advice. Kellymom is great, and you can call 1-800-la-leche to find a local number to call a LLL leader, but if you can line up an IBCLC that is obviously the best.
I read at least 2 BF books and millions of Kellymom pages and links and attended LLL meetings regularly before my dd was born, and I still REALLY needed help. Some women don't. My mother infuriated me on about day 3 (I was crying, trying desperately to get dd into position to nurse) by saying, "when I breasfed you, I just put you to my breast, I didn't need any fancy Boppy pillows or anything." @@ Well, I do hope you are that lucky!! But, in case you aren't, you need a game plan. Asking for advice on the internet is OK if there is really no other option, but it is really impossible to know *precisely* how best to advise someone if you are not "on the scene", so to speak.
I had many loooong conversations with a LLL leader and she was GREAT but what really ended up helping me be successful was the LC observing me try to breastfeed.
However, again, I don't know your particular situation so I am really not trying to make you feel bad if you are in Siberia or something and really have no access to an IBCLC. There are obviously many great resources, like this board, that you can still access. The thing with breastfeeding is that it is trial and error. And a board like MDC with so many different women posting on it will have lots of great suggestions for you to try, if you do run into difficulties. I wouldn't assume that will be the case simply b/c your nipples are flat or inverted, but it might not be a bad idea to get some nipple shields just in case. (I tried e-verting the nipple myself, of course, but dd would not latch onto it - the shield was really a miracle for us! but, many women with f/i nipples won't need it. It's kind of an insurance policy!)
Best of luck to you.
