hello Tommyball007, welcome!
I am of a like mind with londonbus1 mostly.

But, if you are thinking that it is all too much for you, it may well be just that.
However, with help from folks on here at SCF the chore and toil and work seems like a lot less and actually fun as you share and learn from people who really care about stamps and people.
With all that said, when you sell a collection you usually get a small percentage of what you can get by spending some time and learning about what you actually have (and whether it is rare or common or a forgery for heaven's sake do those exist? Yes for anything expensive, they do) and selling it piece by piece.
When you sell things bit by bit in smaller pieces (more common stuff) or one at a time (if they are that good) then you can more closely realize the full market price of a thing, whatever it is.
If you want to sell Now then you will never get what the catalogues and books say a thing is worth. Because those who buy from you will want to sell the things again and make a profit probably so you will only get 5 - 10 % of it's worth.
But when you pick and choose and sell the good stuff one at a time you most likely will do much better. Time versus money.
The good stuff sells well, the poor stuff doesn't sell, even if the catalog makes you think it should. Supply and demand.
If you have better uses for your time at this time (I can't imagine really) take some pictures of things or a quick inventory before you leave it all at a dealer you trust or was recommended by someone you trust. Otherwise, stay with it and just sell it off in small chunks.
The study of stamps and letters and envelopes and cancellations and everything to do with postal communications is a vast and most interesting use of one's time. If you aren't learning and making mistakes you aren't living.
If you have access to a scanner or a camera then please upload some photos or even to a photo-hosting site like Flickr or Photobucket or Imageshack and post a link on here and ask what we think in general and the responses will be most helpful.
