Some changes to our Social Engine site

We want to make some custom changes to our social engine site. 1) the arrowchat module is installed and working well. We just need some permission changes to it for Gold and Regular members. Gold members should in the arrowchat module be treated like regular members. Regular members should not see gold members in chat and gold members should not see regular members. Both gold and regular members only see store members in chat. Gold members should also see the 'start videochat' link that regular members now see. 2) Add a simple Payment Gateway for offline payment by bankaccount. It should just show a button 'transfer by bank'. When pressing that button, going to a socialengine page showing text instructions on how to transfer money. The instruction should mention the $$$ amount that the user selected in the previous menu. It should also mention their member ID and member name in a custom message for each customer to put in the bank transfer description. Add a 'confirm payment' link that sends an email to admin, notifying us that a customer says he made a payment, and giving the payment details ($$$, name, member ID). 3) Disable showing the 'start videochat' videolink temporarily. 4) Make sure to start your reply/offer to this job posting with the sentence: "An apple and a pear". So we know that you read the description fully. 5) Make a message in the arrowchat chatbar that only shows when not logged in: Signup or signin to chat with GirlBump members. With a working link to signup/signin link. If this job is done to our satisfaction, we are happy to give more jobs. We're looking for a developer who does a good job and is dependable and available for more jobs afterwards.
