need a Joomla programer for doing a website work

procurement services site that emails quotations on letterheads of various suppliers to the prospective paid up buyers. The subscriptions should be time bound. 1 dollar per day for buyers and 25 dollars per month and 100 dollars for advertisers. I need the website to be made functional. Payment will be done externally by either bank transfer to an account i will give or via a local mobile payments service. Once payment is done the buyer will be issued with an activation code that will activate the account. Once the account has been activated there will be a timer that will start to count down. the activation codes should be in two types. 1 day and 30 day. for suppliers , i need each supplier to open his own account, make payment , once activated he can then add products and prices and insert his logo and details which will be reflected on his quotation every time someone chooses any of his products. So in actual fact each supplier will have his own account with different details from the next. Supplier the output for the buyers should be quotations emailed to the registered email address as an attachment in pdf format and un-editable
