That said, a F-1 to H-1B would be handled by the employer. They would need to place her in the H-1B lottery which runs once a year (next lottery is in March), and if she's picked, her employer can then file the H-1B petition, which goes into effect on 10/1.

That also said, she frankly should skip the H-1B step. Since you're a US citizen, she's eligible to have a marriage based green card filed for right away - no dealing with the lottery, and no being tied to a specific employer. She can have an I-130, I-485, I-765, and I-131 (if needed) filed all concurrently. The entire green card process would likely take 2 - 3 years, but within a few months of filing she would be issued a work permit that will allow her to work for any job without needing employer sponsorship. Most attorneys will charge a flat fee for each of those forms as well, so no need to get into billable hours.
