For the money, for two years, depending on the amount of members its not too bad, but never accept a sales persons first offer, they will probably take off up to £400 just to get the deal, however, for the money and if you have little work coming in at the moment, you can do a lot more with it, rather than sponsoring a hole.
My advice would be spend the money on generating immediate business, and look at a 3 month role out, then maybe start to look at static or branding advertising.
