Nobody can offer you this. It is not possible in todays market. Unless of course it is oversubscribed like crazy or they are making up lies to give you excuses on how it is possible. Best you can get for 100mbit is 3k from cogent.
it's $3k a month if you're reselling the line (say if you're a webhost or dedicated host). it's $1k a month if you only need the line for company/internet access use (which i DO believe includes being able to host your own sites).
the $1k a month lines are probably heavily monitored to check for more outgoing than incoming b/w or something like that.
