The programmers are have now travelled to work together in the same room. I just spoke to them and they aim to be complete within 3 days from now. They have expressed they fully understand the requirements, and that all the complex parts are already done. The rest is just straight-forward coding and testing.
The deadline before their bonus decreases is 4th May. After this point, the bonus decreases by $2000/week for each of them, until there is no bonus. The deadline is extended whenever I receive software to test. So if I take 1 day to test, then the deadline extends by 1 day.
Will it be fully complete in less than a week? Personally I doubt it because there are always annoying but non-critical issues that you didn't expect, and they slow progress. But certainly they have a strong incentive to make it happen ASAP.
