51867 SEO maintenance job

My site has about 200 pages of good content, but its search engine performance has been very poor, especially lately. I believe Google just did a link update, and my Google traffic dropped by 90%. I need to give my site a little SEO kick in the pants. 1) I have already done keywords, descriptions, titles, etc. on all my pages. I believe most of this work has been good, but some of it could be improved. So some adjustments to these SEO factors are needed (most of which I could do, but your advice would help). 2) I don't need every page optimized. I would like to "re-optimize" ONLY 12-15 important pages at this time in order to get some SE activity generated, and hopefully the other pages will be found via spiders. I don't have time or money to redo all 200 pages. 3) What I really need is somebody to manage search engine submissions (where this is needed) and ranking analyis/strategy for a couple hours a week over the course of the next 4-6 few weeks. I have ignored this part of the SEO process and I need help here. 4) My site is Europe travel related, so it is a competitive area, but my site is good and importantly I know most of the keywords that are good and that will work for me. So you won't have to come up with many new keywords, since I know most of them. So, I think this is a pretty easy job...just to help me coordinate some SEO activities for a few weeks. Since I am so busy, this has been neglected and my rankings are poor or deteriorating lately, so please help. Please post comments on PMB. Thanks... FYI, The site only has 10-20 inbound links now. After a link building activity the last two months, I will have 50 more very soon. I could always use more links if you want to try this as well.
