Some Advise for my Sales Funnel...

Instead of the same tired 'freebie' tricks, why don't you use a REVERSE FUNNEL instead? Basically, build TRUST and AUTHORITY with your readers by giving them free info on your pages. Once they are ready to move on to the 'GOOD STUFF,' they have to sign up. You already earned their trust and established credibility before they get to this point. See the difference from the 'standard model' of giving away freebies in exchange for their emails? The standard model is basically just saying 'hey, buddy, can I spam you legally?' It's old.

Another approach is to offer 100% commissions on a PLR package and collect email addresses this way from sales generated by affiliates.

IMO you should always get the URL of your product name as it makes everything look more professional.

Link the product graphics to the header graphics of your sales pages too. There's no need to have header graphics on your squeeze page as long as you've got a shot of the product you're giving away, though.

Videos are often a good way to upsell. Most people seem to like videos these days.

As for pricing, it depends on your market and where your customers are coming from. You need to do some market research for this.

It looks like you're new to all of this, so I suggest keeping prices low because you haven't built up the trust of your customers yet. As Writeaway says you should help build trust through an authority site, like a blog in your marketing name. Then lead them to the squeeze page through that.

Finally, yes, Paypal is an easy start for setting up sales pages providing you know how to handle HTML or are using software which allows you to insert a Paypal link or BuyButton. If you're not then you might like to try e-junkie or 1ShoppingCart.
