hello welcome to the forum!!
I personally cant recommend any consultancy or agent in the PH because i am not in the PH right now, but have you tried to visit the UKBA website regarding student visa requirements etc??? i think it will be easier to read and understand and do all the processing on your own.
good luck .

heres the link for you to read:
