Copywriter with Awesome Sales Page Skills

Hello and thank you for taking a look at my project. I have a website which needs a very good sales letter. the site is aimed at online merchants who would like an edge over their competitors You can see the site here and hopefully its self explanatory or is that my first big mistake? [login to view URL] I've never engaged a copywriter before so I'm not too sure if there is any special procedure other than to please give me relevant examples of your work and I do not make upfront payments. Thanks again, hope to hear from you soon Regards Don
