MailerLite Expert

I am currently using WordPress and a few plugins for newsletter creation/sending, a referral/ambassador program, landing pages, pop-ups/ins, and a "daily page" that publishes the days' email to the website as a webpage.  I am looking to switch many things over to MailerLite. The website needs to remain but I am looking to switch the email sending/creation, subscriber management, referral/ambassador program(will need to switch to sparkloop), add email verification with MailerCheck(new), then I also need to replace all forms/popups/landing pages and have them connect to mailerlite.   There are just a few email sequences that need to be moved over and I will need help with a new template that is similar to the current template along with the new ambassador program links(sparkloop) and a few other features mailerlite offers, and then lastly if there is still some way to create the "daily page" out of email content. I can give you the current link as an example. I will need to make sure there is no downtime and everything is completely tested before it is all set to live as well.  Please let me know what you think it will cost to complete everything.
