Your profile doesn't say much about you or your family. I was looking to see if you had a husband. You can clear a tree without a husband, but I learned a long time ago that two can do this kind of job a lot easier than one.
Go out into your neighborhood and see if anyone is cutting down downed trees. If they are ask for their help. You might even find someone that will cut it up for the firewood. If the tree is oak or hickory or mesquite, call some BBQ restaurants ans see if they want the wood for their cooking. They may cut it up for the wood.
What kind of tree is it?
You can do a lot to make it less expensive. If you can't find a neighbor to help, Go to Home Depot and buy a good prunming saw, good pair of loppers and two pair of hand pruners. Find out how long branches can be the city will pick up. Start cutting the branches up in those lengths. Its not that hard to do unless its 100+ outside. (One set of hand pruners is for your daughter so she can help.)
If friends and neighbors come over to help be sure to get their names and invite them over for a "thank you" BBQ or deliver (home made!!!) chocolate cookies to their homes.
Good luck to you and yours.
