Hi,
I have experience with accessing many of the publicly available databases you mentioned (NCBI, Ensembl) via their web service interfaces.
As my understanding of bioinformatics and genetics in general is quite good, I am confident that I can provide a seamless interface to whatever data processing needs you have downstream (or also assist with downstream processing, if so desired by you).
My hourly quote is high high, but I am very efficient. If you wish we could also discuss fixing the amount of time spent on particular components, so that you'd effectively be paying by result achieved, and not by hours worked.
Best wishes
Alexander
