i have a tgp but im not a guru. if i was starting a tgp today i would do the following:
buy a copy of autogallery sql
get that all installed (very easy and very good manuals and support)
build the html pages the way you want them and create your submit page, rules and recips.
then you can do one of two things:
1.) list a bunch of sponsor hosted galleries until you start getting submissions.
2.) go to russian submitter and submit your tgp to them and recieve submissions from them.
the one thing you will never have to worry about is getting submissions. there are a dozen auto submitter places out there that will send you more galleries than you can review in a day. dont make the mistake of getting your tgp listed at too many of them or you'll end up getting swamped with 3 thousand gallery submissions per day.
and 2 peaces of advice i will give you about reviewing galleries:
1.) if you run the autogallery sql gallery scanner and it says "page content has been changed" or "thumbnail count has been changed" - blacklist the domain. theres no reason why a pages content would change unless the webmasters is up to something.
2.) if you see a webmaster submitting 50 galleries a day with 50 different domains - blacklist them. the multi submitting is usually the beginning of a scam where they get 200 galleries listed with 200 different domains and start redirecting a few domains at a time every few days to trojan, pop-up, virus hell. and they use stolen content anyways. its usually pretty easy to spot these guys because they give very generic descriptions - they always submit to the teen category - and they only have about a dozen different gallery templates that they use over and over.
more information than you wanted probably but... im in a talkative mood tonight

good luck with it.
