Web portal for staff, work schedule posting, credit card processing, file download page

I am looking for coder to build a website for our new company that will be opening up once the site is complete. The site will be for staff and customers to come to and gets IT pc repair services. Staff will be able to login, post the times available for work on their own page. The page will be integrated into a master scheduler for the control master so he or she can see who is available in a geological area with in the united states to go do a service call. Once an appointment is made for a staff member, a text message will be sent to the staff member on their cell phone informing them of a service call has been scheduled. They will be able to respond to the text by putting in a code to confirm the call. A new text message will be sent with a new code so when the staff member is at the location, he will text that code to confirm he or she is onsite. Within the staff members schedule screen, he or she will be able to see the appointment and be able to process the invoice for the customer while onsite with a credit card. There will be a place to make notes in the invoice before processing so that the tech can explain what was done, or parts purchased. Once the invoice has been paid, an email receipt will be sent to the customer via email with all regular credit card processing information on it. There has to be a page where staff can download some files for work purposes. After they login to their own screen. There has to be a page where the staff can send and receive an email from the site domain. After they login to their own screen. There will be some other generic pages that will be for informational purposes only for customers. IE Company, Services, Contact The master scheduler screen where all staff members are listed I will need to know the staff members qualifications on the fly on the control maters screen. So I will have to see their skills by clicking on the staff for that area. The site can not be right clicked to be copied or see the page code. THIS IS A MUST. After staff login, all pages have to be secure. THIS IS A MUST. The site has to be tested, and approved by us prior to payment release. Site has to be build with in a reasonable time frame. Please post your questions, time frame, and amount needed to build the site.
