Hi,
I'm extremely interested in completing your project for you. As you can see, I am a new freelancer to this site which is why I have bidded so low. Please do not feel that this will effect the quality of work that I carry out; my fee is purely low so that I can build experience and a reputation on this site.
The issues that you are having with CSS sound fairly simple to fix. I would be delighted to look at the CSS file for you. I'm extremely passionate about web development and will not be satisfied until you are completely happy with the results that I return.
If you would like to see a certificate I obtained of my CSS proficiency from an external company, please do not hesitate to contact me and I would be happy to send it to you.
I hope to hear from you soon.
Kind regards,
Sam
