Come join FIST.
Here's some (actually a lot of) info about us:
http://cybernations.wikia.com/wiki/FIST
We have plenty of tech sellers, and we have an area for doing donation deals. if you can pay standard price (9-12mill) for a $20 donation, then you could probably get some. I know there's a few people in FIST whom do donations.
I'm not sure how we could help a nation as large as you in terms of money to grow, but I'm assuming you mean mainly tech and donations, where we could probably help quite a lot.
FIST is a black team alliance, but you can stay on yellow, because you're 58k NS.
We're still fairly small (50 members), and there would be opportunities for you to come gov in the future, if you are an active player.
You won't need to be a bank (in fact I really wouldn't want you to be one), but you'd need to have 20 nukes in case of war.
Loyalty is a must. If you want to "try" out alliance for a short while, and find out that it's not what you wanted and leave - I won't mind, but if you leave when we go to war, I ain't goina be happy.
