Although you might have taken what i said negatively, honestly i meant it with your own interests at heart.
For example, you say that it will be a non profit thing, great but that means that you personally will be dealing with applications, sending out van decals, examining certificates, adding new members to the website everytime someone joins etc,
how long will you do that for basically zero money before you say to yourself "why am i doing this?" Other associations have fulltime staff that deal with the admin stuff for a very good reason, its time consuming. Will you be doing this instead of doing your own window cleaning work is what I mean, will your own business suffer as a result. If so it will be only a matter of time before you pack it in. (or worse yet, if you plan to do it in your spare time then it will be only a matter of time before mrs nathaniel says "its me or the guild")
N offense mate, and my hat is off to you for trying, but i dont think you've thought it through. You just cant run sumit like this for a fee of £1 a month, as neil williams rightly said.
