Bro... you need to make connections with a few TGP owners. Get some partner accounts and work hard at this. It's not what you know, it's who you know.
People like myself submit anywhere from 1-5 galleries a day, to over 40 sites that all have given me preferred submitter accounts. This means guranteed listing.
I do use Adult Submitter to submit my galleries. It's a semi-auto submit that makes things go by a little faster, plus it adds recips, etc.
I also use gallery templates that I can simply drop content images into and upload to my server. Once you devise a system and get comfortable, you'll pump out galleries like nothing, and you'll have the advantage of partner submissions (if you don't cheat webmasters).
Keep working at it, read some tutorials and find some sponsers that will give you nice, unsaturated content to promote with. That is the key.
