A user friendly landing/squeeze page development site with membership options available

I would like to get created a landing page development site where users sign up with a certain amount of money ( various membership levels - monyhly payments or one time payments ) and can make/design landing pages and squeeze pages, etc for themselves to use. Example websites which do this include: [login to view URL] [login to view URL] [login to view URL] Please let me know what you can and cannot do or what your thoughts are. I can even make arrangements to pay you commissions on my sales I make from the site for a certain amount of time and a certain percentage. Remember, I am not looking for someone to design me a landing page. I am looking for a development site like the ones listed above. If you need login names and passwords for the sites, please contact me so you can see what the backend looks like. Please send me an email and not just a bid. And please, talk to me about the site I am looking for, don't just send me your portfolio link or automated link that you send everyone here. Thank you.
