Hi,
Saw your requirement for a BA. I am happy to inform you that we have done similar work in the past and we have qualified and experienced Business Analyst who will do this job. We have experience in preparing SRS, FRS, BRD, As-Is/To-be and Wireframes.
We use different tools to create professional documents like FRS/SRS/Validation Summary/As-Is/To-be/RTM. Please drop us a message to discuss further and also we will show you our sample work.
Thanks,
