Getting affiliates and have great tours and join pages is a combo thing that you will have to work out.
As for designers I would say talk with Czarina.
www.wedesig.net she is the best and does the work herself. She does not outsource like others. She has done amazing work for many of the largest programs out there.
As for the affiliates, You kind of need them to pay for designs and what not.. But on this board you can get some affiliates by posting a couple of pics a week with the program info in your sig, as well as in the post. Also make sure to hit other boards but stick to their TOS about photos.
If you need some great sites to UP Sell in the members area, I have a TON of them for you. or if you just need some more advice or info.
