Hi Kenny,
As long as you have met, have proof that you have met and have proof of regular communication since your meeting, like emails, yahoo chat logs and letters you should be OK, so don't take any notice of the consultant, it's much better if you do it all without the aid of consultants or agents.
All you have to do is download the list of requirements that you have to submit for the visa from http://www.vfs-uk-ph.com/ and then glean as much additional info and tips as you can from http://www.british-filipino.com/ , then if there's anything you don't understand, are unsure about, or would like more detailed advice about, you'll find the members here are always happy to help.
Iain.
PS: The one thing the consultant was correct about is the chances of getting a visit visa. The success rate for this kind of visa is extremely low.
