In one way I hope your post is serious... but in another way I don't.
Buying a TGP when you don't know anything about traffic trading is probably a bit risky. (Unless it's a 'real' TGP, with permanent trade links and no blind skimming - then the traffic probably has more long term value)
Is it 7k per MONTH or 7k per day? If it's the former, that's not really a lot of traffic at all.
How much did you pay, if you don't mind me asking?
