Need misc insulation work for a home project in UK

Hi, I’m planning a small home improvement project and need some miscellaneous insulation work done. The job involves assessing a few spots in an older terrace house, sealing gaps around ducts, and adding a thin insulation layer in an attic hatch area. I’d like someone with experience in basic DIY insulation, who can provide recommendations and use appropriate materials. Access is straightforward, and I can supply insulation bats, sealant, and weatherstripping if needed. I’m hoping to schedule a session during weekday daytime and would prefer a tidy, safety-conscious approach with minimal disruption to nearby rooms. Please let me know your hourly rate and any preparation I should do beforehand.
