Not too far away from you, there are several furniture stores who will kit you out partially or completely.
Torrevieja - Hnos Garcia and Muebles La Factoria also Arca. Hnos Garcia are just up the road from Carrefour heading into Torrevieja. Service and prices are excellent and will deliver (free). The also have a shop on the old Torrevieja/Alicante road. Opposite that store is La Factoria and can highly recommend them. Going to this shop you can park up and visit a couple of stores on same side and across the road. Arca specialise in full fits and have packages depending on the size of the property. Their basic package is just that, basic, but you can swap and change. Also do the full white goods and stove package including fitting. They will also do your lights and other fittings. We got the 2 bed package and it is good enough for holidays but we had to get rid of the sofa settee (too uncomfortable to even sit on, let alone sleep) and got a good quality cotttage suite from La Factoria at an excellent price and free delivery. Arca also sold us everything we need in a pack including cooker, pots and pans, plates, kfs, toaster, kettle, every type of glass you can mention, water jug, iron, ironing board, cruet set etc etc etc for around €450 provided you take their furniture package (we got the furniture free as part of the moving in but still got the pack for the same price). They were also excellent (and quick) at fitting the lights and cooker. I know they deliver to La Marina because someone else buying were from there.
One of the towns near Quesada (can't remember the name of the town but I'm sure someone will jump in) has a glut of furniture stores all providing full packages and made to order furniture. Wish I could remember the name of the town but it's close to Quesada/Rojales. All the one we looked at did free delivery. Bought the cottage suite on a Saturday morning and they were there first thing Monday.
Not sure if La Factoria did the white goods, though.
