I would like to say a big thank you to those who helped me and provide valued information especially zimba88.
His suggestions on employment and Investment gave me lot of confidence and hope. Solicitor wasn't aware of them at all

The main point I focused was not to left any important but avoid sending unnecessary documents.
Keep your file simple. I submitted last one year's business bank statements. The format for FPS was same as provided by zimba88 in another thread. No employment and business contracts were submitted.
Best of luck!
