Answer: Regarding enforceable monetary obligations, a commitment to use a worker is not binding unless an act of kinyan was made or the worker came to start the job (Shulchan Aruch, Choshen Mishpat 333:1). Coming to give an estimate does not count, but to do preparatory evaluation can count. If due to your agreement to hire Reuven, he turned down another offer and he cannot now find replacement work, you must pay based on the damage your job offer caused (ibid. 2). However, it is rare that a job that takes a few hours and the worker chooses the time would require such a worker to turn down another job (see Pitchei Choshen, Sechirut 10:(9)). If any of these grounds for obligation might exist, we cannot give you any sort of ruling, without both sides presenting their sides for us to rule.
If there was no binding obligation but one did not keep his word, the mishna (Bava Metzia 75b) says there are ground for tar’omet (being disgruntled). This is parallel to mechusar amana, when one backs out of an agreement to purchase something, and this is a (serious) moral deficiency.

Another relevant matter is Reuven’s high fee. If a po’el (roughly, one who is paid by time) overcharges, the homeowner cannot void his obligation due to mispricing, as a po’el is analogous to a slave, to whom the laws of ona’ah do not apply (Shulchan Aruch, CM 227:33). The Shulchan Aruch (ibid. 36) rules that ona’ah applies to a kablan (one who is paid by the job), like Reuven. On the other hand, not all agree (see Maggid Mishneh, Mechira 13:15), and according to some, ona’ah does not apply to work done on something connected to the ground (see Pitchei Teshuva, CM 227:26).
On the other hand, the question whether ona’ah applies or not may be irrelevant here. Regarding the case of mechusar amana, the Rama (CM 204:11) cites two opinions as to whether one may back out if the transaction is no longer worthwhile because of a price change. The final p’sak is unclear (Shach ad loc. 8). The S’ma (333:1) reasons that the same opinions would apply to a worker’s possible tar’omet. The Aruch Hashulchan (ad loc. 1) says that an employer may back out if he found out the worker is unqualified without the moral stain of tar’omet. Similarly, if one found out the work was significantly overpriced, this should be grounds to remove the tar’omet even if the formal rules of ona’ah do not apply.
This being said, it is hard to trust one partial opinion, like that of Shimon, to conclude that Reuven is objectively, grossly overcharging. Perhaps Shimon needs the job badly and is offering a large discount. Maybe Reuven’s work (regarding what he has planned, how he performs it, or materials) is on a different level than Shimon’s.
In summary, it is likely that you are not morally bound to employ Reuven, and in a case of doubt on a moral, not legal obligation, there is room for leniency (see Chashukei Chemed, Sanhedrin 67a). On the other hand, you might consider the lack of clarity, both about the halacha and the story, and you do not know what points Reuven might raise. Therefore, it would be noble to discuss the matter openly with Reuven. Feel free to contact us again with your findings.
