I agree totally with Paris re the move.
We all know there is always an initial flurry of interest no matter where you are and who you are advertising with.
You could move and then find that bookings decline drastically and you may find that you are in a more expensive flat with less expendable income and you are struggling.
If you still have the same volume of clients after say six months I would say go for it but definitely not in the initial months of new advertising, it could be financial suicide. You could always save in the first six months while you are getting the extra money in but remember it is Ireland you are in and through time the time wasters and no shows WILL start appearing in the cracks as sure as cheese is cheese.
