your joking he wants it done every six months, the blokes who done the inside said to me after, "now i've done it for £150 what did you charge?", when i told him he nearly collasped 
we both messed up with that, he said he'd want 150 to do it next time cos of all the hassle he had. he reckoned it ahould've been 5-600, talk about rub salt in the wound 
Yeah we've all been there one way or another, but it makes you learn fast
Lesson learnt do not pay subbies in cash, on invoice basis only
if they only accept cash, do not use them. Did you actually see their insurance details when you agreed this?
You made £81.00 so this equates to £27.00 per hour, not the best rate, but certainly not the worst around!
So lets get it right for next time....
1) are you able to do the whole job yourself and how long would it take one person to do, if only one day then £231.00 is ok. At that rate to take 1.5 days is alright
2) If you have to use a subbie again, can you not use someone different? You can then agree new terms!
3)Look for a subbie that will do it allfor perhaps £180-£190, that way you still earn against it whilst you are out earning elsewhere
