What you think about this idea for design services?

Hey indiehackers,

I just curious to know this idea will work or its stupid as hell for design services...

IDEA:

What if there is design service that sell its design services like food stall:

example

• when customers comes on your website they see your services like

Logo $50

Landing Page Design $100

HTML CSS $150

Branding $300

and so on.....

So user can add what they want in cart and checkout with custom selected deadline time and pay.. so design service work on deliver your product on time..

and if want revisions give 2/3 free and if want more ask for some $$$ as it goes!
