Hello - I understand you want outsiders professional opinion and suggestions for improvement of your new website. I am experienced web designer, having more than 8 years of experience - during those 8 years I have been working as designer, front-end code, design consultant - All relevant positions.
So, this job is something, i really can do. I'll take some time to go through the website / find out anything which needs obvious improvement, implement it on a jpeg to show you, and if you like it, I would implement it on your website.
After it; l I'll present you a list of things needed to be changed or improved.
