So far I have found these.

But they're DIY tutorials. I cannot solder to save my soul.
are there any companies that can do this for me? Will I have to buy the pedal (s) and send in, or can I just buy them already as modules? I would prefer the first, but would use the second if I had to. Honestly, I would use either if I had some more money.

On my shortlist are the basics:
overdrive/distortion
screamer
tremolo/wah wah
chorus

but I am open to anything
