> Hey there! First of all - Thank You. By agreeing to find a mutual time on our calendars, you've saved both of us at least 3 email exchanges and a lot of frustration. Secondly, please go ahead and select a time and duration that works for the purpose of the call. In case you don't find a convenient time slot for next 5-7 days, ping me and I'll open up additional time slots for us to connect. I'm very eager to speak with you! Looking forward! Cheers ~ Palkush
