Hello, I am looking for some advice from people applying for positions related to Web Application Design/User Interface Design, basically - Front End/Web GUI development

I am having SERIOUS PROBLEMS convincing the hiring manager/interviewers, that I have the required skills (XHTML/CSS/Fireworks/Photoshop/UI/FLASH, etc.) because they don’t see a good portfolio with working live prototypes.

My beef with this is a lot what I have done is NO LONGER UP LIVE,
1. Either the site design has been changed/redesigned
2. Or the page(s) was on a temporary domain (a landing page or microsite, or email campaign)
3. Or the application interface was internal to the Company/ITDept

And I am screwed either way, because either my portfolio is weak or I don’t have the related experience/language to get the job or I don’t have experience in any other field to start at entry level (like sales/marketing or finance or other technical, because I don’t have a BA or BS, I am completely SCREWED

We send business emails to potential clients, once in a year. But, of late, a number of business emails sent are thrown out, considering them as spam. The very purpose of sending mails are lost. How to reach the targeted persons without being thrown out as spam?
