Agree with the replies above. You’ll get plenty of good, practical input on here, but it really depends on how specific you can be about what you need.
At the moment it’s quite broad. “Mentoring” can mean anything from basic startup guidance through to sales, marketing, pricing, systems, etc. If you can narrow that down, you’ll get much better, more targeted advice.
If you’re looking for more “back to basics” support, there are also some good free options:
- Local Growth Hubs (e.g. Gloucestershire Growth Hub and equivalents across the UK)
- Bank-led startup programmes and workshops
- Local councils / enterprise partnerships
They won’t replace hands-on, paid support, but they’re a good starting point.
Given you’ve said you’re a bookkeeper looking to market yourself, I’d suggest you’ll get more value here by asking very specific questions (e.g. “how do I get my first 5 clients?” or “how do I differentiate from other bookkeepers?” etc).
What’s the one thing you’re struggling with most right now — lead generation, positioning, or converting enquiries?
