Dave
Welcome to the Wannabee forum and congratulations on completing the training!
Whilst we are delighted to help folk get a foot on the first rung of the ladder it is expected that you do a bit of research - to help you we have an excellent "Search" function.
You will find that the questions you asked have been asked and answered many times before - and quite recently at that. If you read through some of the threads you will find out more about the parlous state of the industry at the moment and you will be able to make up your own mind.
If I were to let the thread run it would attract a lot of the sciolists and give them chance to spout their favourite monologue so I'm closing the thread.
Good luck
HWB
