PAID JOB - need help with integrating cakephp apis

I will advertise this on freelancer, but I giving genuine cakephp programmers a first look at a job I have with integrating cakephp and APIs. I have cakephp skills but not much API integration.

Its integrating a current cakephp crm with APIs like Xero (already done ), quickbooks,myob and also vido conferencing APIs like zoom,wiziq(already done), and other things like mailchimp,sms apis
Will need to demonstrate you can do this as i keep getting people who just say yes to everything and have no/little experience with this.
