mandelbrot, its strange for them not to give details of practitioners and I don't understand how those prices even cover planning/carrying out a full statutory audit on any company no matter whether small/missed deadlines or not trading etc. In my experience those type of clients usually took more time as were not prepared for audit so you usually end up doing the books before auditing, prior year figures become an issue, non attendance at stock takes etc as not appointed at year end and higher audit risk etc. One off jobs like that are a headache & not profitable unless they turn to repeat business which is hard to predict.
I took the liberty of searching using the CRO auditor search facility - a quick search reveals a sole practitioner firm primary contact is a Shaheed Mamhmood, a CPA.
Op what is your ARD. have you missed ARD completely ie ARD+ 28 days has passed? if within 28 days submit B1 online on day 27 & that will buy you extra time (3 wks i think)to submit signed B1 & unaudited accounts.
if 28 days have passed it is worth a grovelling call to the CRO to explain why deadline missed, if good reasons eg one shareholder/director & illness or death in family etc etc they might just might give you a one off extension to ARD
