Lots of credit unions have the no fee 0% BT and 0% promo offers. You just need to find them. I don't carry balances at all, so I can't name a lot of them off the top of my head, but I see them frequently.
Keep in mind that you will spook your creditors if you get several new cards and suddenly max out the credit lines, and they may take adverse action against you by either lowering limits or closing accounts. This is even for accounts and creditors that you have without a balance.
Don't let any card report 90%+ utilization, and it is wise to keep it below 70% (the next FICO utilization bracket). Below 50% is even better to avoid AA.
