3k is a very small amount I must say...
what you need to do is feed your tgp over 14 days or so while you are building trades. maybe 60% to galleries and 40% to content. I myself have better luck with going 50/50.
with 50/50 you should be able to build the tgp to an initial 20-50k/day and then you just have to try and keep it in that area when you take the feed away

That's the hard part
Anyway
you can buy traffic from TrafficHolder.com if you don't do so already
See my sig.
