Custom Quote Templates in Excel

I need quote and invoice templates created in Excel. I already have basic ones created, and understand how I want to format them, however I just need extra tables adding and some additional formatting so sums and data entries carry through pages and tables.

Requirements:
- Itemized list of services/products
- Total cost calculation
- Client information fields

Design should incorporate:
- Company logo (already have this ready)
- Custom color scheme (colours and scheme ready to go)
- Preferred font style (Chosen)
Most of the template is complete and ready. Just needs a bit of time tweaking. Ideally will have a video call with expert to discuss requirements and show where I am with things currently.

Ideal skills and experience:
- Proficiency in Excel
- Graphic design for branding integration
- Experience with creating professional templates
