Build a Website -- 2

I have a wordpress website running on Enfold Theme. I have a Seperate CRM system on the same domain I would like to create a button on the top of my wordpress site called Login. When users click on that, a dropdown of 2 fields, EMAIL AND PASSWORD should appear. Users should be able to type in their credentials and click login and the system should login to the CRM System. Upon Login, i want the webpage to display the following message Welcome Back - NAME OF CLIENT (obtained from the CRM system ) Please wait while we retrieve your records ...... (animated dots ) GREEN TICK Successfully loaded your records .....(animated dots ) GREEN TICK Redirecting you to your members portal ....... (animated dots ) GREEN TICK The page should then redirect them to a page in my wordpress with an iFRAME of the CRM System ( This is already done, but i need the iframe to be in full width. Currently it appears to be only in the center of the website ) I prefer a freelancer with the relevant php/wordpress knowledge instead of some companies to do it. Its a simple job, please do not quote skyhigh prices.
