If you can't do the conversion yourself then I would say sell the car and buy a golf gti instead, labour isn't cheap for an engine conversion, but you would be looking at around £1k labour alone.
Also when you add on the buying all the other parts you need like coilovers, brakes, and the labour to fit these parts too, it's just not worth it.
A conversion is never meant to be a cheap solution, it should be done without worry for expense as an idea, re-sale shouldn't cross your mind and neither should any concerns arising from problems from a conversion, you have the inevitability of problems if you pay someone £1k and bought the engine for £1.2k and find the engine is no good then you should be able to afford to have them take the engine out, buy another one and fit it back in.
That's why most who do the engine conversion can either financially afford to do it and look after it or they know how to do the conversion and look after it themselves. I would say advise you to buy a gti instead they can be had for around £2000 anyway
