split the money into 2 and send 2 custom offers of 30 days each.
If you mean duration, this is not possible. 30 days is the max. As sofia_writers mentions, maybe creating two offers at 30 says each (with the 2nd being purchased after 30 days) is probably the best solution.
If you mean creating an offer which stands for 60 days, offers have no fulfillment time limit on them, so you could create and offer and manually withdraw it after 60 days if not fulfilled.
