Help Required Urgently!!!!

[nsm2010]

Hi all,
My HSMP visa was stamped in October 2007 with postponed effective date from December 2007. I came in the UK last December 2007 and suppose to file my FLR in November 2009.
Since last August 2007 I have been redundant because of the current recession, before working 07 months on 48000 annum job, which was more than my actual target of 40,000 a year to fulfill requirements in FLR.

Recently I have been approached from Middle East (overseas) ,where I have experience of more than 12 years, to assist them in one of their project, as a consultant. They are going to pay me a hefty salary against my services to them.

I want to know whether I can show this income as my legitimate income while I file for FLR?

Whether this income would be accepted and I can earn points against it?

Is it necessary that I should bring this amount here in the UK?

What documents would be required to show this income as legitimate income?

How long could I be absent from UK since this job will required my frequent extended trips to the Middle East?

I will appreciate if some help me in this regard.

Thanks in advance.
