Firstly, as he stated, he was advised to put it in 5K blocks.
Secondly your bids are not going to show all bids at that price, only one or two blocks at that price. There are blocks higher than the .075 bid, so obviously its not showing all available.
So as rasta said, place your buy and you will get several transactions to equal your total transaction as there are lots of blocks out there at .075.
