The OP should ask a upfront question.
Have you ever performed a playfield swap?
If not, this is a even deeper different level of added experience to build entire games.
Having built games from scratch, parts availability is different today, and much harder for oddball requirements, not considering special mounting bracket fabrication.
Bottom line: This is not a project for novices, and you will easily spend $7K+ BoM, and still be missing crirical components for added costs. Personal labor cannot be estimated unless experience is known.
Good luck.
