Hello Freelancers, I need a few modifications to this script that I have installed. You can visit the links below to get an idea of the environment. [login to view URL] (front end) [login to view URL] (backend)(login:Username: admin Password: guruscript) I have all the code already installed, so just the code will need to be modified. Here are the modifications that are needed: 1.) Change the pay structure so that my client is not involved with the payment process between the freelancer and employer. 2.) Setup the script to function so that they bill the freelancer only in two ways either a.) flat monthly rate b.) Per bids that are placed for their projects. (if b. is not doable, then please suggest another way that a payment structure can be setup to bill only the freelancer not the employer. This environment will not be used in the traditional way freelance clones are used for. It is being used to put accountants in touch with potential clients. So that is why it will be paid for by the "freelancer". I really need this completed asap, so please bid if you can complete the project within 72 hours. Thank you, If this project goes well, I have some other work from you also.
