ask the exchange you are willing to deal in they ideally will direct you to recommended providers.
it has been a long while since I used them, but I remember RTS = real time systems (i think) and ORC software, were two.
re contracts - every one is different. it depends on what they offer.
plus dont forget you are then competing against in house built systems, and then it becomes a technology race.
