Another option would be a 1.8t. A BAM lump can be had for under 1k now and as standard it has 225bhp. Qpeng can supply an ECU with switchable map (225 - 260bhp) downpipe and all the other bits required.
If you are paying someone to do a conversion then I would spend a bit more and get a 1.8t, go on, DO IT!
