Training Consultancy

I have found a Training and Research consultancy that i really like the look of. Its fits all my deal criteria and as I am an ex consultant understand the space and business model well. However i was initially looking for a more 'blue collar' service industries and wanted to see if anyone had any strong views on this sector or those who have acquired in this space. I am aware of the inherent risk associated with consulting business but wanted to see if there was anything i was missing??
