hey SI. sorry this has to be so challenging.
1. monster.com and jobs.com are 2 sites you can post your resume in your location. you already may be familar with these sites. idk.
2. talking with employees may help too. sometimes they know of openings.
3. the more sphagetti you throw against the wall helps too...meaning swamp your area with resumes. include a cover letter.
4. even if you obtain a part time placement it can lead to full time employment.
5. forget your areas of expertise but if memory serves me well u have a couple of directions you can go so have multiple resumes depending on job description to emphasize the area they are looking for.
6. always follow up with a thank you letter or email to the hiring person. it may put you in front of others just by your name being once again in front of them.
7. being currently employed in any field helps one obtain another job. employees like to see an employed person more than non-employed. go figure.
8. if a resume is not gaining u interviews you need to "switch around" your resume to see if the changes bring better results.
9. temp agencies..may eventually get you a job offer from whomever you're doing temp work for.
my background helps me offer you these suggestion, fyi.
hope some of this helps. idk.
