I'm not looking to get rich or take advantage of anyone. I would give a number if I was familiar with the currency rates in-game. Essentially I was hoping to have some freedom to buy things now and then in the early game until I started making money myself.
I was offered 250,000 from a very nice person that was a pleasure to talk to, but they are on the EU servers. Seems like a lot to me, but I don't know. It's certainly not a suggestion or benchmark.
Whatever you would be comfortable with.
