Now let me see the full Service model and the DEFAULT_SERVICES in the store:

Now I have the full picture. I need to:

1. Add hours field to ServiceItem and a "free" tier concept
2. Update DEFAULT_SERVICES with hours per service
3. Update OfferConfig to support "free" tier
4. Rewrite the offer view with editable prices, hours, and free option

Let me update the store first:

Now update DEFAULT_SERVICES with hours and free tier:

Bump the seed version:

Now rewrite the offer view with editable prices, hours per service, and free tier option:

Now let me verify no type errors with the old "starter" | "growth" | "enterprise" references remaining elsewhere:

Clean -- the only reference is the new ServiceTier type which now includes "free". Every service now has hours per tier (manually adjustable), editable prices with inline overrides per selected service, and a Free tier option across all 14 services (including 2 new ones: Local SEO and Graphic Design). When building a proposal, you can pick any tier, override the default price/hours with custom values, and the PDF includes hours columns next to pricing. The summary bar shows total hours alongside costs.
