Put in all the Paperwork in you can is my advice.
A letter from his employer would be great saying what a good worker he is this should help to show job security.
My Wife had in her paperwork NBI clearance, and other local paperwork which i have forgotten the name of which showed she had paid all her taxes up to that date etc. We added certficates and reports from her education.
Swamped them in information they can't then say oh we need to check your nbi clerance or oh we need to check that you have this qualfication you claim to have etc.
Regarding co sponsering im pretty sure they can't be used in uk applications, its down to just the sponser and the applicant. I might be wrong and its worth reading the UK visas website (which has huge amounts of information on it if you have the time (i myself spent hours reading it at the time of our application)
One way they might be able to help if they could help you find work.
With regards to camille sheryls application she wrote details which were most useful on at least two websites the links to i don't have at the moment on this pc.
But basically with regards to her savings she just showed proof she had them (ie her bank statments) which were good enough it appears for the british embassy.
Im not sure what others think but if your hubby is just in the black and it can be shown his account is going in the right direction your savings should show yo can support yourself and him if required too!!
Maybe others can clarify but its both the sponser and applicants combined assets which are being assessed?
