Theres nothing worse than having to have gone through a lot hard work for prospective clients in the space of just a few days then it becomes a Waiting game to hear back from anyone.
In some cases they have taken six months or more to get back about the job if at all and you have to keep digging for information on whether you can put all other things aside and begin work on the Project or go elsewhere. One thing is certain don't wait just move on to another job because if you become dependant on the outcome of one job you will get Nowhere!!. If it is positive then weigh up your options and see which job will be the better for YOU!!
