if you want to lead, embrace the "Director of IT" title and play up the fact it was an SMB if you're going for a relatively low level leadership role (team lead, etc).
whatever you do, get rid of the phrase "tech lead". i've yet to meet someone who described themselves with that term that didn't make me go "this fucking guy"
What is the job title on your contract? That is really what you need to cite.
Follow the advice given by others about the structure and grammar on your CV and, yes, talk to recruiters who will give you a realistic opinion on your options and salary expectations for your skills set.
Good luck.
Edit: Wanna roasting?! £60K for what you are doing is quite reasonable unless you are in a location such as London, in fintech or have a unique skills set - which doesn't come across in your description or writing style.
Happy to discuss elsewhere if you wish. FWIW I am in West Sussex.
