Validating idea: productize design service with Figma

Hello friends, I want to productize our professional design service with Figma and I came up with some ideas and thoughts:

• We deliver a complete Figma file with all the important sections: moodboard, sitemap, assets, components, wireframes, style guide, mobile version, desktop version, and more...

• We have an expert figma creative team.

• We create with a focus on UX and Web Marketing.

• The complete design process takes approximately 1 month per client.

• We can make all the revisions that the client wants until they are satisfied.

• We will launch with 3 plans: startup (one page + blog), growth (5 internal pages + blog), and company (+5 pages + blog).

• We start with a value of 500 usd for the "Startup" plan.

• Then the client can choose what to do with his design in Figma. You can choose to create it with Webflow or with code.

• We can add that additional programming service to create the website in case you do not have another agency or team.

• We also deliver a complete documentation in Notion with templates to help the client to create the contents of the website and to learn marketing tactics for its growth.

What do you think of the idea? Would you hire a service with these characteristics and prices?
