I will charge you $35/hour. I'm among the most experienced and skilled Excel, and VBA developers on this platform. In particular, I am in the top 2% of the freelancers having completed over 320 projects successfully in six years, and I feel confident in achieving your task as well.
I'm online from 8 am to 9 pm, Athens time (including weekends).
I'm looking forward to working with you.
Sincerely,
Paris Pallas
