PHP Database development required

Hi there, My name is Chris. I am a university Student who is starting up a tutoring business. I am in need of a database which allows me to: - Enter Student details into a form - Enter tutor details into a form - When I enter a new student in the database, I would like a function which would allow me to search for suitable tutors in the database based on the Student's year, hourly rate & location (using postcode or a google maps integration- or any ways you know) - Allow me to create invoices & receipts which will be saved on the tutor/students form, which can also be saved as PDF and emailed - Creation of profile reports of each student/tutor which can be saved as PDF - Allow a table within the student & tutor form which allows me to enter any payments they've made me- may be used from the invoices created I currently have an access Database which does a few of these feautres, however, I would like something where multipe users can login into, and the data will be saved automatically. Also, I have a website where students/parents send an enquiry form- I was to be able to send this form data directly into the database. I would also like a payment method (2Checkout or another gateway besides PayPal) i can pay my tutors from, which will record that I've paid them into the database. I am just starting up my business, so the maximum I can afford is $400. Thanks very much. Kind Regards, Chris N
