Awesome - I PMed you some info on our DISchurners site as well as some biz card application tips! I think the "list" of cards you'd be interested in are:
- Chase Ink Preferred (CIP) - biz card
- Chase Sapphire Reserve (CSR)
- Chase Sapphire Preferred (CSP)
- Southwest Business Card
- Southwest Personal Card(s) - there are 3 of them
Since your husband is interested too you can alternate applying for cards and even refer each other to cards for extra points! A CIP card for you now would be a great start while we formulate the rest of the plan. That signup bonus is 80,000 Ultimate Rewards (URs) for $5,000 Minimum Spend Requirement (MSR) in 3 months. That signup is worth somewhere between $850 and $1,275 depending on how you redeem the points!
I don't have any "support link" available on CIP currently...but PLEASE consider supporting one of our great DISers when you apply. You can find a support link on our DISchurners Reddit group (which I PMed you about).
