If you already have a semi-established business, you are looking for an employee and not a co-founder. "Looking for a technical co-founder" implies you are starting a brand new business, not looking to bring someone in to an established business.

My intention when I posted was to leave my existing business to run itself and to apply to YC W15 to found a new business.

Having reflected on the advice and the fact I don't have a technical co-founder I know and trust implicitly I am going to go down the route of hiring a competent technical advisor to PM this for me with sub-contracted work.
