Frequently Asked Questions

How is the cost of services estimated?

After our initial meeting, which can be conducted online, I create a concise project brief that outlines the requirements and scope of work, along with a rough estimate of the cost. Once we are in agreement regarding the budget estimate and timeline, I then prepare a detailed proposal that breaks down all associated costs and prices into separate milestones.

Are you open to handling smaller projects?

Of course! I appreciate small projects as they allow me to get to know my clients from the outset, building trust and cultivating valuable working relationships.

What guarantees can you provide?

I offer a 12-month warranty for projects with well-defined scopes.
