Right, so you can create a startup that contracts these hotels and sell your contacts to bedbanks like Hotelbeds I guess? I haven't been in touch with the industry since a while, so I can't give you too many specifics advice.
A few years back, I remember a startup building a portfolio of Mediterranean(If I recall correctly?) hotels and end up selling the company to a bedbank for 30 Million USD.
If you are not looking into making this into a full blown business, I guess you can take a cut as an agent by hooking up the hotels with the representatives of the bedbanks. Look up for people titled "Market manager" and see if you can arrange a deal with them. Market managers are people responsible of adding new hotels to the portfolio of a company and manage the relationship with these hotels, they usually make good money from commissions. It also often involves things like resolving errors with the booking software, teaching the staff how to use the interface etc.
