I guess my question is which route I should go to help get the most points.

As an example, AA Citi for 75k points for $3k spend, then get a business AA citi with 30k points for $5k spend. Getting these two cards might tap me out with Citi.

Then use the starwoods personal card for 50k for $3k spend, then get the business one for 25k points for $5k spend. Then transfer the 75k points at a 1 to 1 to AA and get a 15k bonus. Since these are both AMEX cards, if this rules me out from getting another AMEX card, is this the best option.

Then if these 4 cards are the best options to start with, it could feasibly get me 195,000 point on AA using $16k in spend.

That would still leave me $84k in spend. I also don't know how realistic it is for me to be able to qualify for 12 - 15 new cards all at once.

Just trying to figure out the best option for signup bonus, minimum spends and possible points transfers while keeping in mind card issuers.
