HI,
I have good experience creating software's integrating hotel booking api's. I would like to know more details about your requirements before i can given you accurate bid.
Could you please provide more details, on what all needs to be updated (i understand it is inventory & price, however what about the different room type, etc).
Also do you already have an api access agreement with these providers. Lastly what is the current process you follow, is it manual.
Looking forward to hear from you.
Thanks,
tony.
