Sorry you’re struggling to settle, but you need to give it time - if you still haven’t received any calls two months later, then yes, you’re right to be concerned, but after two days, I think you’re worrying a little prematurely.
It is worth considering that spending money on advertising does not always translate into bookings or even enquiries. If you’re not so much as getting a single nibble, then it is more likely that your ads, copy and pictures aren’t right, but, this isn’t the case, you’re just not getting the clients you want. Look at this as a positive; all the time wasters and undesirables are getting themselves out of the way now, so the genuine clients will soon follow.
Easy for me to say I know, but just hang on there, the tide will turn in your favour.
