I suggest the pair Tinycad + freepcb. Both are free, without restrictions
on size or the number of layers (nowadays, it is next to impossible to use
the fine pitch chips with less then four layers). It is very easy to design
your own symbols in Tinycad, and I suggest you do that. Freepcb has a large
number of standard footprints, and it easy do design your own, if required.
FWIW, I use the batchpcb service for four layers boards - fast and cheap
for small designs.
