Ultimate Tiling

Hi I am thinking of a change of career and think i would enjoy tiling.
My plan at the moment is in this order.

Buy some tools

I cant afford to but top of the range tools straight away so would look to get a mid range set of tools first then replace as I do more work.

Practice

I will read up on Tiling methods to get a better idea than a diy'er and do some free work for myself and family, I work for myself now so after a few freebies start getting some paid work.

Course

When i am confident and earning a few quid from paid jobs invest on doing a course maybe nvq2 and replace tools with more pro gear.

I am a taxi driver at the moment so I can still earn bread and butter money at weekends until Tiling takes off.

Does this seem like a reasonable plan or should i be doing things in a different order (ie Course first)

Thanks Andy
