It's very difficult to predetermine a credit limit prior to submitting an application for a card. Generally speaking, one strategy is to call the card issuer directly and actually tell them what type of limit that you are seeking and the amount that you intend to transfer to the card. The idea is to tell them upfront you want to do a transfer of X dollars and they will be more inclined to do it than merely basing their credit limit on traditional credit scoring methods, letting their own greed get the better of them.
From my personal experience, however, you rarely, if ever get a credit limit that you're really looking for. While I'm not advocating lying, I would encourage you to stretch the truth
by significantly "overestimating" the credit line that you actually need and the amount of money you'd like to transfer. The card issuer will no doubt come up with their own number but hopefully it will be more in line with the credit limit you were hoping for.
