This is a bit complex, but probably not more than 2 or 3 days of work. So, do not place a bid unless you have expert-level Joomla knowledge and have designed components for Joomla in the past. Oh, and you will need to be ready to start this project right now. Do not want to talk with anyone who will start next week. You must be able to start today or do not even bid. No brokers. Will only deal directly with the person doing to coding.
Will discuss component details in the PMB.
Thanks for your bid.
The budget is low in this specification and do not expect anyone to deliver this for just $250 - but you are welcome to surpise me. More than $250 is fine and we can discuss your price in the PMB. But, be reasonable or you will be ignored.
