The VentureOne (not the Venture, which doesn't have a 0% intro APR) seems like a strong option, as it doesn't allow approvals for toy limits (the minimum approval is $3000). The downside though is exactly that -- that you might get saddled with a $3000 limit, and unfortunately Capital One is rather rigid with initial credit lines even if you are willing to take additional hard pulls for increases (FYI, most of their CLIs are SPs, but often require 6 months before granting them). It might be a bit of a gamble to withstand 3 HPs for a card that might not end up suiting your short term needs and you really aren't even concerned with keeping long term anyway.
A Citi credit card might actually be a considerable option. To warn you ahead of time, Citi is not the easiest lender to get in with and their credit lines usually start rather low (especially, the Double Cash, reputedly), but hear me out. Citi is generally very generous with CLIs upon card activation if you are willing to give up another HP for it. It is rather normal for a person to only be approved for a $2000-$3000 credit line with Citi but get it bumped up to $6000 or more with an additional HP. My thinking is, if you don't get the credit line you are looking for upon approval, you are rather likely to still be able to get the limit you want with Citi -- it just depends on how much you are willing to give up. As for your best 0% option among Citi cards, you have plenty of possibilities: Thank You Preferred, Simplicity, Diamond Preferred, and Double Cash (my personal favorite), just to name a few. All of the aforementioned cards also have the benefit of not having an annual fee. As for being approved in the first place, your AAOA is a bit low, but your scores are high and your inquiries are low (Citi is particularly inquiry sensitive). I suggest putting your info into Citi's prequal and see what comes up.
