Continue developing a matchmaking website

Alif and Ain is a Muslim Matrimonial website. It is currently live but we will launch as a company on 1st May 2016. [login to view URL] Most of the functions are done, but there are a few outstanding issues that need to be resolved. We have stopped working with our current web developer as he wasn’t fit for the job. OUTSTANDING WORK 1. We need a good database program (at the moment, the website is hosted on Wordpress and so we are managing our database from Wordpress), as we are matchmaking people based on their requirements for a spouse and so we need several search filters to narrow down our clients. Currently, we can only use one search filter at a time which will be very time consuming. At the moment, all the clients are test accounts as we haven't launched the company yet. 2. We need some slight changes in functionality on the backend, including payment. 3. We need to make sure the mailing list is integrated correctly for different functions of the website so that users are receiving the correct emails at the right time. 4. Payment - we need to set up payment for credit/debit card and PayPal safely. 5. We also need some kind of security so that people can't hack into our website and steal our clients data. 6. As part of registering to our service, users will need to upload a short video of themselves (10-30 seconds) and we need you to help make this not slow down the process of our website. Our previous web developer integrated a video function, but it slowed down the website. Deadline is asap. We will need our web developer to be ready to make changes as and when we need them over the coming weeks and months. As we grow, we will need our website to become more sophisticated, so there is likely to be more paid work with a bigger budget in the near future. Many thanks.
