So we own a "Topsite" website and a gaming server with a website userpanel.
What we need is a system which can be integrated into our Userpanel, where the user (choosing for which character he wants to vote) can vote, is forwarded to the "topsite" and after he has finally done the "voting" he receives a "session" called "done with the specific site he voted for" (this can be done depending on the ranking nr of that specified server)
now when he returns to the website of the game he has voted for, he will be forwarded to the userpanel and will receive special items ingame as a reward. We already have a similar system like that for another "Topsite" so you can probably look at it and copy a lot from it.
If you think you can manage this, bid for this job. Since it is mostly copy-paste I expect fast delivery and not so high bids. Bid your last price! we will not negotiate later on.
and ONLY propose with a specific text about this project, we will not hire people who dont read the requirements.
