Help me finish my studies

I started mechanical engineering studies in Estonian Univercity of Life Sciences in 1998, I reached almost the end but.... my studies were interrupted for going to work therein. I tried to do 2 things together but it wasn't possible - salesman work don't gave me much chances to be in univercity and finish it. My economical situation made the decision for me - I needed money for living. Now I have a serious plan to finish it and change my life. I have only 4 subjects to finish, some exams and the thesis work with final exams. Seems not a lot keeping me away from being graduated univercity student and turning new page in my life. I have at the moment period in my life where I can use time for its intended purpose, but.... theres always some but, I don't earn enough to pay for living and also for univercity.

I add here a small introduction of univercity:

Estonian University of Life Sciences is the only university in Estonia whose priorities in academic and research activities provide the sustainable development of natural resources necessary for the existence of Man as well as the preservation of heritage and habitat. According to QS World University Rankings by Subject (2015), the Estonian University of Life Sciences is one of top 100 universities in the world in the field of agriculture and forestry, ranked 51 to 100. The university also belongs to the top 1% most cited research facilities in the world, with our plant physiology professor Ülo Niinemets being the most cited Estonian researcher altogether.

I hope for your charity and help to turn a new page in my life.
