i also had the call :

i couldnt beleive my luck, my wife rang me and said someone has just left a message and theyre looking for someone to do contract work for local council and police, i was like, woo cool. so i rang and hes like "yeh loads of council work bla bla bla"
im thinking great whereabouts, then the "just a £99 a year fee" that stopped me just like that, i just went dead...was like "hmm" and "ermmm"
and he asked if id like to check out their website i was like go on then
they keep ringing but i wont answer
£99 for something that isnt actually there and might be
MIGHT MIGHT MIGHTsod that, ive got enough work, i not gonna pay some random company telling me theyve got loads of work for me and then saying "oh actually there isnt actually any work at the momment but there could be and youll get it and all for £99"
