Currently looking for someone to help me finish a task that was just suddenly given to me by a client which is a rush job , i got this project that wasnt finished because of my negligence of time and working hours so i need someone to just hack it together just to make the thing work as i am currently busy with another project. the webapp is currently made in rails currently resides in github that is hosted via heroku, just basic rails html with bootstrap , i didnt include all the shit that needs to be done as i was underpaid for it, and was also rushed. i need someone to implement a pagination of an email listing form inside the landing page which should be connected to the client's mail chimp account API and after pressing send , the email that was put in the paginated page should send data from the webapp to the mailchimp list with the senders email address. then a confirmation alert should show that their email was added into the mailing list. i physically cant do the job as i am very much tied up at an android project that is needed to be done within next week so i cant code this one, i need to you help me out , i have already setup all the API information that you will need for the project, and will also give you the permissions that you need to be able to push the changes into the project
