marketing- paypal payments

I have few sites already on no.1 position but I need to get more sales. So I am open to suggestions to what you guys can do and let me know your price as well. Our products are covers for boats, rv, car and silk trees.

You are very misleading in your title.

If you are asking someone how much they would charge to put paypal buttons
on your site???

If this is the case dont. Its really simple to put these buttons on your own site
paypal will guide you through creating a button and then give you the HTML code
for it. and you can just copy and paste it into your html file.

I really didnt understand your question you might try rewording it
