Dave,
I think you'll find that the majority of couples on here applied themselves, and did not use the "services" of an agency.
The forms are straight-forward, and all questions have either been asked on this site (use the search facility and/or read threads), or you'll get an informed answer if you do need to ask.
As JB states, if yours is a simple case, then save your money ... you're gonna need it later (for FLR and ILR) !
