Pre seed - any viable alternatives to SeedLegals? I will not promote

​ SeedLegals were quite cost effective when they launched, but their prices keep increasing. I'm in the process of preparing for SEIS and a pre seed. There is a few complexities in our SEIS application that makes the self application not a good idea. So I'm considering resorting to them. I'm wondering there might be any viable alternatives to SeedLegals in terms of value for money and success rate? Is there any other route that SeedLegals these days to prepare for pre seed with SEIS?
