Does anyone here have experience doing F Reorgs or a 338f?

We are acquiring an LLC via a stock purchase (certain complexities prohibit us from doing asset purchase).

The company is a SaaS company, and we plan to acquire it using a C-Corp to take advantage of QSBS opportunities in the future.

Any experience with F Reorgs we should look out for, how much should it cost?

Any good professionals you could recommend?

Any disadvantages for the seller?

Any other simpler options to depreciate stock purchase like an asset purchase?
