Was Offered a Job if I Moved, After I Moved I Was Not Hired

[antoniollanito]

My question involves employment and labor law for the state of: Florida
We use Common Law

Stanley works as a managing supervisor of a large computer software manufacturer in Dallas, Tx. He receives a phone call from Oscar, the owner of a rival software manufacturer in Florida. Oscar asks Stanley if he is interested in coming to work in Florida and offers him a job at a higher salary and better benefits. Oscar tells Stanley that Stanley can only accept this offer of employment by traveling to Florida and signing an employment contract there. Stanley tells Oscar he is very interested but that he will have to talk to his wife about it first.

Stanley and his wife discuss the matter that night and they agree to move to Florida and take the new job. The next day, Stanley quits his job and tells his old boss he is moving to florida. Stanley then drives from Texas, costing him hundreds of dollars in gasoline. When Stanley arrives in Florida, Oscar tells Stanley that he has changed his mind and has now offered the job to someone else.

Question: Was there a valid or enforceable contract between Stanely and Oscar to allow Stanley to sue Oscar's company for breach of contract?
27 minutes ago - 4 days left to answer.

Additional Details
I was thinking it was a Unilateral contract because there was a promise given in exchange for some action.
The Unilateral contract is formed only when the action is complete.
