Looking for a software developer ideally in UK

We have a small SAAS app that’s based in VB, I think! Our current developer is stopping so we need someone to take over maintenance of the app with some small updates every now and then. It’s a simple financial forecasting app. The previous developer didn’t have to spend much time with it so we’re looking to set up a retainer with a developer to look after. If anyone is, or knows someone, who might be interested, please get in touch.

Can you define ‘every now and then’ please?
As a developer, I know that this can mean anything from once a year to once a week…

In the last year they set up an automated https certificate renewal and fixed a bug with the password reset feature.
