To me that means that you think that it should be written, but you haven't actually stated who is going to write it (though they would have to be idiots not to figure out who you want to write it!). How about, "I'd like to come forward with a proposal that I write it." or "I'd like to propose that I write it, myself." or "I propose that it be written by me." Personally, I like "I'd like to write it." Then, when they insist on a proposal, I would say, "OK. I propose that I write it." Though, there is a sense of underlying frustration evident there which would not endear you to a roomful of committee members who thrive on administrative jargon.

Ummm... your sentence sounds less formal than "offer my services", and is fairly awkward. Is there a reason that "offer my services" is not suitable?
