What is the Best and Cheapest cost website builder/Hoster?

I agree with Richard, $10 per month is not enough for what you want. Free and overly cheep solutions may work more or less well but all of them has some weak sides. I think website builder named GetSocio.com is one that offers features that are pretty close to what you need:

- It's a hosted, pre-built and customizable solution for building ecommerce sites. You can create you site very quickly and you don't need to take care of hosting and many other technical issues. You can easily update and customize your website at any time.

- You can pay a certain amount of money in advance and the commissions will be taken from your balance on a pay-as-you-go basis. If you run out of you balance your site will be blocked but your debit card won't be affected.

- There is no limit on hits.

- Security: if you use a default domain (yourwebsite.getsocio.com) your website will be protected by wildcard SSL certificate. If you use a custom domain name you can buy and install your own SSL certificate to protect your site.

- There are many integrated payment gateways so you will be able to get payments from your customers via PayPal, Authorize.net and other payment processors.

- Your website will be indexed by search engines.

The pricing slightly exceeds your requirements: the cheapest plan costs $15 per month + a transaction fee but still it's quite affordable.

They have a really good website building platform as well as integrated, secure and affordable hosting (branded sites are free and their paid plans range from $6-20 per month).

Their security is very good (I use them for projects often) and while they don't support credit card payments they do have integrated PayPal features. They also let you edit your websites HTML tags and metadata for really good Search Engine Optimization.

You could start a free blog through Blogger or Wordpress. There is no cost at all and you could write about your cause, why the movement is needed, where your idea came from and so on. Blogger is the easiest to work with in my opinion. Once you get the blog ready to roll, promote it for free on MySpace, Facebook, MyBloglog, the opportunities for that are endless. Hope this helps.

Your expectations seem reasonable for $40 to $50 a month minimum but not for $10.
