If you need to buy 300k hits to "jump start" your TGP you are doing something wrong.... if i was you i'd learn how to design a TGP that has 300-500% productivity before spending a dime on traffic to "jump start" it. With a good design you should only need like 10-20k MAX to get up to 100k in no time...
Please just retire and go sell some rock to make the rent sorry for being so harsh but you are just not cut out for this biz.
