Before I discuss the "go sailing now" option....here's a link that will show you some furler packages and their costs.

Okay, two quick things to do and you can go sailing tomorrow, without spending $1000 or more installing Roller furling unit and a new sail to fit it.
First, rig a "jib downhaul" with your hank on headsail... It's very simple... a length of 1/8" line tied to the top hank on your sail (not the head, or shackle) with a buntlline hitch.... run down to a small block shackled to the tack fitting, then run back to a cleat near the cockpit. I ran mine along the toe rail through a couple of bullet fairleads clamped to the stanchions (you'll need these anyway when you finally get a RF unit)
The jib downhaul will keep your sail secure on deck by keeping the halyard and top of the sail from bouncing around before you're ready to hoist. But it's greatest benefit is that it allows you to control the drop of the sail....
The second thing is to rig some lacing between the life line and deck from the pulpit back to the second stanchion on each side. You can use the same size and type cord you used for the jib downhaul.
The lacing keeps your sail from sliding off the deck.
So... when you want to drop the jib, you can head up and control the drop with the downhaul, steering the foredeck under the sail as it comes down and drops between the basket created by the lacing on the life line..... Or... downwind you can ease out the boom and shadow the jib, pulling it down quickly with the downhaul when it floats over the fore deck.
I single hand all the time on my 27 footer and this inexpensive addition to my rigging a few years back made my life so much easier, and safer......
You'll need enough line to cover the luff of you jib and the distance back to the cockpit, a small block with a shackle and an inexpensive clam cleat for the down haul. Probably not more than $30. The lacing can be accomplished with a bundle of nylon, braided cord picked up at any Home Depot for less than $10....
This open, mini camcleat is under $5.00 at WM.
The Ronstan series 20 block with shackle shown in my boat pictures below is under $17 at WM also.
The pics below are from my boat showing how the downhaul line is tied on, where I fixed the block and a look at the sail lying on deck, hanked on, safely between the life line lacing, ready to hoist.
