its a sign of pretty desperate times if someone with 10k hours is going to buy a type rating on a midsize. Are you considering it because you hate what you are doing now? Sometimes I wonder if the change of career from airline to corporate (or the other way round) is driven by a grass being greener sentiment. If so, it's probably worth pointing out that at the moment there isn't any grass anywhere...
stay where you are and wait for things to change. A proper job on a midsize will come with a rating - the commitment should always be both ways.
