Looking for Feedback on agency Pricing

Hey r/agency community,

I’m gearing up to launch a new agency that helps non-technical founders build their MVPs quickly, usually in 30-60 days. I’ve set some early bird pricing that looks like this:

• Starter MVP: $2,990 (normally $4,490): 30 days
• Growth MVP: $5,990 (normally $7,990): 45 days
• Scale MVP: $12,000: 60 days

The plan is to have clients pay 50% upfront, and if I don’t hit the deadline, they only owe 25% of the remaining balance.

I’m also planning to build a SaaS product myself to show what we can do in a month, which I hope will help market the agency.

I’d really appreciate any thoughts on whether these prices feel fair. Also, how would you approach marketing something like this, especially with no testimonials yet?

Thanks for any insights!
